Thanks, this is really interesting what can be done with QB64. Cheers!
RE: 3d surface images - james2464 - 12-26-2022
Got my first model import working. Not the textures, just the shape.
The data is in the attached text file. It will load this file and then create a new file "convert.txt". Then it reads that into the program. I'm not sure this is the best way to do this but that's what I came up with for now.

End SubRE: 3d surface images - MasterGy - 12-27-2022
the cat turned out very well! I look forward to further developments!
I haven't tried it yet, but in principle texturing works in such a way that the second member in the "f" lines is "xxxx // yyyy", so yyyy specifies the location of the point in the texture image. If you load an arbitrary image in its place, you can set how much of the image to zoom by multiplying yyyy. I don't know if it's understandable. So far, I've only used texturing by writing a separate program to see the model, and I can specify which image to assign to each of the triangles. But if you want to display the model completely realistically, you should try to use the original textura-font defining values, i.e. the second members in rows F. Good luck !
RE: 3d surface images - MasterGy - 12-27-2022
SMCneil !Don't be upset that I'm only now answering! I'm also in a lot of development, and I do that when I have time. Maybe I'm getting it right. Not sure. The idea sounds interesting. After the holidays, and when I'm done developing my new program, I'll try to make a program you came up with.

Thank you for explaining, I'll try this. Should be interesting to see the full 3d model in QB64, complete with texturing.
This has led to a different idea. Until this 3d model test, I thought _maptriangle was only used for square images. Break the square into two triangles and then put back together into a square, after some transformation. But this 3d model test was only using triangles. So only 1 _maptriangle was necessary.
Anyway I wondered about making a terrain map, using random numbers. If I could just take a square texture image and split it up into triangles, then modify the z points up or down. And to my surprise, it works! I then added water to make it easier to view.
