Lesson 16 Comparing Floats Turns out... floating point numbers are never quite what they seem. Program idea: write a program to test if a float variable set to 1.1 will be evaluated as equal to, greater than or less than 1.1 When that is known, add tests to the program to see how little needs to be added (or subtracted) to the explicit value to make the evaluation with the variable come out differently from before. Program idea: A bit of code like this will show that a floating point variable set to 1.1 will evaluate as greater than a literal 1.1 float myVariable; myVariable = 1.1; if (myVariable > 1.1) { cout>> "myVariable is greater than 1.1"<< endl; } Write a program to test how little the literal 1.1 needs to be increased by to change the above outcome. Lesson 17 C++ Conditions Conditions allow you combine multiple small decisions into one big decision. Program idea: Think of a job that has several qualifying factors. For example, an astronaut has to be in certain height and weight ranges Write a program that prompts the user to enter their values for the factors and then tells them if they get the job. If they don't qualify, tell them which category(s) they missed on. Extra credit if your program has a use for both && and || @Roger @Shelton @Rodney

el Toreador!

I can confirm the problem, which seems to have originated a few betas ago. I'll make a report. Thanks! Note to me: the last version this works correctly in was the one I downloaded on 10/31/2022

v18 handled the missing images more elegantly, so I did this render in that. Yes, I think turning "Transparent AO" ON will get you the result you are looking for.

I wasn't able to load the PRJ because it is calling for several image maps. Images are always external to the PRJ file. However... first... do you have Transparent AO turned ON? If you already had that ON, can you make a version that needs no images, or otherwise, attach the images here?

How's it going, @MJL? Progress? Bring it to Live Answer Time on Saturday and we can look at it if you still have questions!

You don't want Animate Mode OFF. And you don't want that Red Border. It's a warning that Animate Mode is OFF. I never touched that. Leave that "not set" Animate Mode isn't about rendering. It's about keyframes you make before you render. Try my sample project and do what i do in the video starting at 21:04 MyronTitle001b.prj

Very old Greek pottery in the late 7th and 6th centuries B.C.E practiced something called "black figure", where they painted imagery with black glaze or "slip" on the red clay. A couple centuries later they reversed that to do "red figure" where they used the black to cover the negative space around the image they were making. After seeing examples of this work at a museum I wanted to try to recreate some of that look, including the numerous fractures they tended to have after being buried in a dump for 2000+ years. Thom is a cylinder wrapped decal. The break lines are a combiner material.

I like all of Rodney's solutions, especially using Groups on one model instead of making separate models. Rodney should visit the forum more often!

You have the "Animate Mode" button turned OFF. That's stopping you from making new keyframes. Turn it ON. The red border on the view window warns you that it is off. It's at the far end of the interface. Either stretch your A:M window out or move your button panels to reach it.

@Rodney on the popup "DataTips"... are you sure you're in full Visual Studio and not "Visual Studio Code" (as Roger had been a couple weeks ago and not getting popups)?

Lesson 12 Bools and Chars This completes our set of classic Data types everyone should know. Idea for project: Declare a couple of Boolean variables. Set one equal to true and the other equal to false. Print out the values of both. Label your output. Declare a char variable and set it equal to a value. Print out both its character value and its integer value. Label your output. Declare a second char variable and prompt the user to give a value for it. Print out both versions of the char value. Label your output. Lesson 13 If "If" is our first "decision structure." We can start getting the computer to make choices. Idea for project: Prompt the user to guess something that is one of a set (e.g. month of the year) and use only "if" statements to tell him if he is correct, close to, or wrong with his guess.

Myron, today at Live Answer Time I did a run-through of the effect you are asking about. The demonstration begins at 6:52 in the video... @MJL

I reported that problem in v19 and have now added your post to the record https://reports.hash.com/view.php?id=6915 thanks!

The easiest way is to make each letter a separate model, then key them in the Chor using their "Active" ON/OFF property. If you want to bring that to Live Answer Time today we could look at that.

Those are lovely, Myron!

I think it's in the .MAC file. I don't know if it can be transplanted. If it's not in the .MAC it might be registry data.

hmmm... When I open it in v19.5a I do get an "Average Normals" switch...

You dragged the STL Prop into the Chor but did you start a new A:M model in the Objects foIder and drag that into the Chor also? After you do that... in the PWS, in the Chor, there is a "Shortcut to [your A:M model name here]", the empty model you dragged into the Chor. Selecting that enables the Modeling Mode icon. Turn that ON. Turning Modeling Mode ON enables regular splining tools in the Chor except... you can not use simple left-click-drag bounding boxes to select groups of CPs, you must use lasso tools.

The information that has to be processed for a CP and the splines that intersect it and the patches they make is much greater than for a vertex and a facet in a polygon model. But now you're converting all those vertexes and facets into full CPs and patches and there is something A:M has to do called "finding" after every CP is added to a spline that seems to take exponentially longer as the CP count increases. My experience is that any model above 10,000 CPs is probably impractically tedious to edit. It's possible that if you wait long enough a 1.5 million vertex model might finish importing but the same can be said about a killer asteroid strike happening or the Sun running out of fuel.

After you import the Prop, you can put it in a Chor and model new splines there, I recall. Drag the Prop into a Chor. Create a new empty Model and drag that into the Chor. Select the Shortcut to Model, then choose Modeling Model to begin editing the Model with new splines. Snap to Surface (Shift + 9), which attempts to place new CPs on the surface of a Prop or other object already in the Chor was made for endeavors such as yours.

Import the OBJ as a Prop.

How are you using this scan? Are you trying to edit the polygon mesh down or are you drawing new splines on top of the polygons?

v19.5 is out now. Having a 19.5 suggests plans for a v20.
