Xtaz Posted November 7, 2005 Share Posted November 7, 2005 Hi Spliners : ill tell about MUFOOF Exist countless uses for the passes, one of them, is the capacity to work with Multiple Frames in Only One Frame ( MUFOOF ). Here i will show you, how to set parameters.. I use it to simulate a fast movement, GI, fire .......... The general concept is to produce an action (it doesn't import how many frames it has) that will be executed in one frame .... The secret for that is to alter the properties of the action inside CHO. First project -> Create a fast spinning helix -> model a simple helix and setup bones ( or download it here ) -> Create a new action , select the bone and select : frame -------- set Z rotate to 25_______________90 50_______________180 75______________-90 100______________0 ->of this you sort things out created a turn of 360 degrees in 100 frames -> import model and action to a new Cho in the action properties under CHO reset : lenght = 1 repeat = 100 ( number of action frames ) and in rendering options set : Passes = 100 (10x10) motion blur to 100% now render the scene and VOILA, you have all your action in one frame Next step will be how to fake radiosity using one light... here is the result ...

sbk Posted November 7, 2005 Share Posted November 7, 2005 That's cool, though the name seemed mildly rude at first glance. Then again, this from the woman who misspelled fluorescent in the title of the post that gave rise to this intriguing lighting method. I claim insufficient coffee at the time of my original post. But MUFOOF is neat. I applaud your luminary genius. S. Quote Link to comment Share on other sites More sharing options...
oakchas Posted November 7, 2005 Share Posted November 7, 2005 very cool! Now a question, oh Lord Of MUFOOF. Sometimes a still of something like a propeller, as you show it, has slightly more "density" in the blur at certain "stations" of the clock. The photo captures the blur of the propeller, as you have , but it is also possible to detemine that it is a two or three bladed prop, because there is a concentration of the blur at, say (for example of a 2 bladed prop) 10 and 5 o'clock... Is it possible to recreate this with your method... or would that have to be done in post? Quote Link to comment Share on other sites More sharing options...
heyvern Posted November 7, 2005 Share Posted November 7, 2005 I think you could figure this out using some math... I can't give you specifics... but... The action can be divided by the number of passes related to frame rate possibly, not sure exactly, to force those propeller "positions" to render "more often" than the others. Or you could have those positions in the action "hold" for more than a few frames... maybe add a jitter at those positions to blur it some more. I had this problem with a very fast pattern moving along... the frame rate was not in synch with the rotation and it appeared to go backwards. I had to figure out how many repeats of the rotation would line up with my frame rate. p.s. I have used the brain cells that contained my math education for Bewitched reruns. Vernon "!"

oakchas Posted November 7, 2005 Share Posted November 7, 2005 I had this problem with a very fast pattern moving along... the frame rate was not in synch with the rotation and it appeared to go backwards. I had to figure out how many repeats of the rotation would line up with my frame rate. In some cases, IRL (in real life) this actually occurs. Does anyone remember the "space ray guns" (I don't really remeber what they were actually called) that shot a ringed propeller off the end of the gun? If you shot it straight up, the propeller disc would sail in the air... but it sometimes appeared to be reversing it's rotation direction in mid flight. By the laws of physics it should not have done that, and continued to go upward, but it certainly seemed to. My father told me that was impossible... (I was, like, 6 or so)... I "proved" it was possible by shooting the disc at the top of the molding above a door frame. The disc spun along the top of the frame, and then reversed direction, but when it reversed, it did not fly away from the wall off of the molding ledge, it merely continued along the ledge in the opposite direction until it fell, still spinning, of the end of the ledge. Anyway, it was an interesting phenomenon, and at ~6, I had no way to explain it... it just did it... and the old man was amazed, too. Pardon the digression.. but I guess I'm saying sometimes things really are as they appear. (Maybe A:M follows these odd laws of physics, too? ) Quote Link to comment Share on other sites More sharing options...
Xtaz Posted November 7, 2005 Author Share Posted November 7, 2005 Is it possible to recreate this with your method.. no problem about that ....

Xtaz Posted November 7, 2005 Author Share Posted November 7, 2005 thanks Oaks ... lets continue Second Project -> Simulating radiosity First step is create a room whit color walls.. in this case red in left and green in right side ... i added a texture in the ground just to enrich the scene ... then I create a new light in room model . You can position it anywhere ... create a new action and then you must position light in correct place, in this case in the red wall edge, set light color to red... then in frame #100 drag light until green wall edge and set light color to green... You can download a zipped file which contains model and action here Create a new Cho, delete all lights and ground import room model and put some props inside it .... relocate camera .... Import room model and action .... in action properties under CHO set lenght = 1 and repeat = 100 in rendering options set passes = 100 (10x10) and motion blur = 100% Voila !!!!!

You would need a Sum() or rather a Quadrature() function for this. It would be simple to have a plug-in calculate the quadrature of one channel and put the result in an other, but it would be much more awkward for the user. I'm not sure the average user will use a Quadrature() function enough for Hash to take the trouble.

Here is my latest idea which is currently giving me mixed results; I take the concept that XTAZ introduces with this thread one step further by instead of assigning the cycle length of the prop rotation action to 1 in the choreography, I assign it the value of a pose via an expression. The pose doesn't do anything except generate a percentage from 1 to 100. I then create an action that changes the pose value over time. By applying both of these actions to the model in the choreography, the cycle length (therefore the RPM) changes over time. So far I gotten mixed results, sometimes it looks like the prop never moves when I render an image, sometimes it does, and still sometimes I get a syntax error with the expression. In short, I need to learn more about expression assignments, especially since I'm trying to assign a variable to a parameter instead of a function.

pixmite Posted November 14, 2005 Share Posted November 14, 2005 I think we're trying to accomplsh the same thing (control the velocity of the spin with a pose slider) If I suceed with my model I'll post it. Well I think I did it, but I’m not quite sure. The reason being is that I’m not quite sure I fully understand what AM is doing, but I have been able to get the effect I was looking for so I thought I’d share. The first attempt, based on XTAZ’s prop model concept from this thread: I created a pose that did nothing and named it throttle, and then in an action I changed the pose value over time. I added this action to the chorography and set the cycle length for the prop to be an expression whose value is set to the pose value. As the animation plays out, the cycle length was changing in accordance with my action, however it didn’t seem to have any effect on the model. The velocity wasn’t changing. I’m guessing that AM may only look at the cycle length parameter of the chorography when it starts, so despite the fact that I was able to dynamically change it, my model only seemed to respond to its initial value. The Second attempt (the one that works, I think): I added a second bone to the prop model (calling it throttle) to which no control points are assigned. I then created a throttle pose, which scaled this new bone in the Z direction. I set the Z rotation value of my prop model bone to the Z scale value of the throttle bone. Multiplying this expression by ChorTime() and a constant I was able to control the rate of rotation with the pose slider. I set various pose values in an action to simulate the non-linear rotation nature of an aircraft engine going through a start up sequence and I got the effect I was looking for!!! Note: Some strange behavior that I don’t really understand: If I reduce my throttle value over time too quickly the prop starts to spin backwards? This occurs before the Nyquist rate is reached. Any ideas what I’m missing/not understanding? If anyone is interested in the modle file I can posted later today. Pixmite Quote Link to comment Share on other sites More sharing options...

This occurs before the Nyquist rate is reached. Any ideas what I'm missing/not understanding? Since you are multiplying the Z scale "function" with the ChorTime() you should expect this behavior. I also had this idea before I realized that setting the RPM with a slider is probably not possible in A:M (for reasons I have explained in an earlier post). What is happening is that when the sum of the derivative of your "function" and the derivate of ChorTime() is negative, the propeller will spin back wards. If you have a propeller spinning at different RPM:s but always in the same direction and plot the absolute angle over time you will never have mixed sign derivatives in your plot. Always positive or negative. Quote Link to comment Share on other sites More sharing options...

aaver Posted November 17, 2005 Share Posted November 17, 2005 [...]tonite i write how i did it !!! no expressions Yes I agree, it's much easier to do this without expressions. The trick is to realize that the rpm is proportional to the slope of the absolute rotation angle. With that in mind, it shouldn't be too hard to control the rpm in your animations even if it would be even more convenient to have a pose slider doing it, was it possible.

oakchas Posted November 17, 2005 Share Posted November 17, 2005 tonite i write how i did it !!! no expressions My guess is that you projected a still onto a plane and rotated that. (plane was attched to back of nose cone) The effect "almost" works... It would be interesting to see in front of a fuselage, in a daylight scene... This might create a problem with how to make the blades appear where there is a black spot now. The "shadow" (dark reflection) on top right of the nose cone (I think) is what gives it away. But I'm just guessing! And it's still a pretty cool look! Something that could be added to a still to make it look like a photo. I wanna know if my guess is good! What'd I win?

Stuart Rogers Posted November 29, 2005 Share Posted November 29, 2005 now ill show how to fake GI using MUFOOF ....There are definite signs of multiple (virtual) lights there - I think you might need more lights (maybe on their own spirals, each with a rotation offset around the y axis). But it's definitely a promising approach!Thats it .....Is that all you have to say?!

How is the spiral light trick... different from other "random" single light actions or "multiple" light sky light rigs? The trick is getting a light in sort of a random spot for each pass... so... is this just another way to do it? Vernon "!" Zehr Quote Link to comment Share on other sites More sharing options...
Stuart Rogers Posted November 29, 2005 Share Posted November 29, 2005 How is the spiral light trick... different from other "random" single light actions or "multiple" light sky light rigs?I think the idea is to get the light to pass uniformly over the entire sky dome. It doesn't have to be a spiral, but with a spiral it should be relatively easy to see that you do get uniform coverage. This could be taken a step further - by modifying the spiral you could hint at non-uniform global illumination. For example, if you had a scene with half your sky clear, and the other full of brooding clouds, you could tilt the spiral over, and maybe distort it towards the brighter parts of the sky... EDIT: By distorting the spiral, I have in mind making the coils closer together at the point where the sky is to be brighter. This could also be done by not dstorting the spiral but the play with the 'ease', so that the light lingers longer at the place where the sky should be brighter. EDIT EDIT: I think my cold's starting to make me babble ... time for an early night, I think. Quote Link to comment Share on other sites More sharing options...
Xtaz Posted November 30, 2005 Author Share Posted November 30, 2005 How is the spiral light trick... different from other "random" single light actions or "multiple" light sky light rigs? Hi Vernon ..... I believe that the main difference among the methods, is the render time ... i did a small test using Yves´skylight method against MUFOOF I used 144 passes to simulate the number of existent lights in the Yves´ dome...that increased the acuracy of the MUFOOF image.. check it ... using yves´s dome whit: multi-pass OFF render=2'52" 2 passes render= 2'55" 9 passes render=7'12" Quote Link to comment Share on other sites More sharing options...

aaver Posted November 30, 2005 Share Posted November 30, 2005 I believe that the main difference among the methods, is the render time I disagree. With all due respect I think the main difference is in quality. With your spiral method, you will never get rid of the banded look unless you have a very large light together with multiple rays from each light, but probably not even then. Your method with a moving light within a single frame was first thought of some years ago and John Henderson addressed the banding problem in his application Scycast. Jeff Lee has also done this in his JSL Skylight Rig Utility Although the methods are slightly different, a static rig like Yves' is capable of producing as good results as a dynamic rig. Yves', John's and Jeff's rigs are designed to cast uniform light from the whole dome, while your rig casts much more light from above than from the sides. If you like to compare the methods, you have to remove most of the lower lights in Yves' rig and you really don't need all the 148 lights to light this scene. My suggestion for a quick comparison would be to use the rig with 8 lights and lift the whole rig so the top light is maybe 150% higher. Set lights to cast 2 shadow rays and render with 9 passes. For even better quality, use the 20 lights rig and 16 passes. My guess is that with the same quality, you will find Yves' rig to be much faster.

DrRIEGER Posted December 1, 2005 Share Posted December 1, 2005 Hello everybody, I'm testing a lot the differents options for a professionnal work with a lot of animations (surgical techniques). I follow this topic with attention, and I have 2 very important questions : Q1 : Under the Multipass subTab on the Rendering Settings Panel, what is the action of SOFTEN ? (the online manual is not clear for me) I made some tests and set soften ON : it increase A LOT the rendering time with no real difference (to my eyes) vs soften set OFF. Here are my settings : Export EXR in D1-PAL Buffers : alpha ON lights ON each light on its layer Render FINAL Multipass : 25 , Soften OFF ... then ON to get a comparison. Motion Blur : 100 % Q2 : what is the incidence of the Motion Blur percentage in this Dynamic Light Rig ? Q2a : Considering I have a STATIC scene with a flying camera. Q2b : Does the reply be the same if some elements in the scene have movements ? Q2c : what is the consequence on the rendering as MotionBlur percentage decrease ? (I just notice that if No Motion is set, this Dynamic Light Rig does not work). Many thanks for the replies. Alain Quote Link to comment Share on other sites More sharing options...
