Tom Goddard August 13, 2024 Modern OpenGL core profiles don't offer line widths except for 1 pixel. On retina or high-dots-per-inch 4K displays these lines are very thin and faint and two pixel width lines would be better. Here I looked at a few ideas to provide mesh lines greater than 1 pixel wide.

Web9 de jun. de 2024 · Yes, in instanced rendering, you typically supply transformation matrices. And this is how you do that in OpenGL: In the vertex shader, you supply vertex position and normal as you usually do, but now you also have a vertex attribute for the transformation like this: in mediump vec4 position; in mediump vec4 surfacenormal; in mediump mat4 trf; WebIt would be much more convenient if we could send data over to the GPU once, and then tell OpenGL to draw multiple objects using this data with a single drawing call. Enter instancing . Instancing is a technique where we draw many (equal mesh data) objects at once with a single render call, saving us all the CPU -> GPU communications each time …
