Hello everyone. After two months of work (intermittently), here is a new post on Videocore.
In the previous post Videocore : textured cube in rotation, we saw how to program the Videocore to display a cube in 3D. The Videocore was responsible for the display, but the compute of the vertices was done on the ARM cpu side. I optimize the 3D calculation, entrusting this task to Videocore directly. To achieve this, you must use the Videocore in GL mode, which allows the vertex shading.
In this tutorial, I show you how to get a move and rotation of shapes step by step. With first, the filigree shape, then with colors, and textures.
The icing on the cake is the interactive demo, which allows you to test on your Raspberry, and rotate the spaceship yourself with the keyboard. An overview below :
