I working on another program for a long time. It has been literally worm by my neck, so I needed to relax. So, What about, projected a normal 2D image in the form of a pyramid in 3D?

Code: QB64: [Select]
  1. image = _LOADIMAGE("dyne01.jpg", 32)
  2. imag = _NEWIMAGE(1024, 768, 32)

It is moving fastest when it is largest and best chance to see details is lost.

Yeah. With close proximity, the GPU has fewer computations and increases speed. Well, I will write something similar and try it better :-D

Hi Petr!
Nice work on this!
For speed, you can try doing this in OpenGL (using array buffers).

Hi Ashish. I like to see you here after a long time! Yes, with OpenGL the solution is here. I'm sure I'll go back to him, but I'll still be doing some attempts with _MAPTRIANGLE. I assume that QB64 problems with OpenGL will worsen over time (because OpenGL is no longer supported by some OS, instead of Vulkan) so we maybe may see Vulcan in QB64 :-D. Yeah, it's more like a dream.

Molten might be the way for us to go in the future:  https://moltengl.com

Quote
Molten GL provides the power to transform your graphics applications and games on iOS and macOS platforms. This premier product from the developers of MoltenVK will run your OpenGL ES 2.0 application or game on iOS or macOS using Metal — and faster!

No need to rewrite rendering logic and shaders for different platforms or abandon the familiar OpenGL ES 2.0 API. Applications built for OpenGL ES 2.0 can use MoltenGL to run on top of Metal, to gain the additional graphic performance of Metal today, and to protect your investments in OpenGL ES into the future!

If OpenGL is going to be loose its support from some OS then, _MAPTRIANGLE will also not work, since _MAPTRIANGLE itself uses some GL commands internally.

We're not removing OpenGL support. Also, everything indicates we'll be back as normal in macOS in the upcoming 10.14.2 version of their OS.

I  also like restoring QB64 functionality to all supported systems. I will add to this thread the transcript of these OpenGL samples in the future. (so if we take Galleon's pattern, it will never be :-D) The display principle is the same (the OpenGL and 3D MAPTRIANGLE coordinate system), of course for 3D MAPTRIANGLE it is necessary to add a lot of already completed functions that OpenGL internally supports, such as a color transition from top to top, or _glrotatef (through modified ROTOZOOM), and I'm not talking about lighting. Again, using _MAPTRIANGLE, it is easier to perform texture than opens in OpenGL, where I have not yet come up with the reason why freeing texture work not right (with gl statement) and where I am very sorry for the miserable internal GLUT support. The tea pot, she sent me to the ground. The reason for her removal is..... and cause UNCOMPATIBILTY....  no, better no comment.

Problem with the buffer and speed, pointed out by BPlus, I assume that the _DEPTHBUFFER command should resolve this issue.

I do not want to hurt anyone here who is trying to support the flourishing QB64. I'm glad for it. Teapot is the only thing I do not take as a step forward. Well, gentlemen, I'm going to go into the depths of the code, I did not have time. I had to change the gutter on the roof. He was already very rusted Yeah. I sometimes do this too.
