Webvoid main () { vec2 uv = vUV-0.5; float angle = atan (uv.y, uv.x); float radius = length (uv); We then increment the angle by the given amount, multiplied by the radius. Next, we convert the polar coordinates back to Cartesian coordinates. angle+= radius*twirl_amount; vec2 shifted = radius* vec2 (cos (angle), sin (angle)); Web7 de abr. de 2024 · When rendering in Texture coordinate (UV) space for special effects or tools, you might need to adjust your Shaders so that rendering is consistent between Direct3D-like and OpenGL-like systems. You also might need to adjust your rendering between rendering into the screen and rendering into a Texture.

WebIntroduction. It is often desired to make a shader that reads from the same screen to which it's writing. 3D APIs, such as OpenGL or DirectX, make this very difficult because of internal hardware limitations. GPUs are extremely parallel, so reading and writing causes all sorts of cache and coherency problems.
