The vertical axes of textures and picture pixels is shown above, when sampling textures in shaders, that is from top to bottom, which is top-right corner. This is consistent with how most image file formats store pixel data, and with how most graphics APIs work (including DirectX, Vulkan, Metal, WebGPU, but not OpenGL).

You just need the following resources and code: A post-processing shader A material with the shader bound to it A post-processing extension TypeScript file for passing parameters to the material Let’s use an example of creating a screen grayscale effect: 1. You can also drag the material into the module’s material slot in the editor.

Preface In the last article , Kylin shared how to add your own post-effect Shader in the custom render pipeline in Cocos Creator 3.8. However, based on the BlitScreen solution, we can only write the simplest post-effect Shader. Today Kylin will use Gaussian blur to demonstrate how to write a multi-pass post-effect shader.

Such pointer could be reported as valid even though the memory it points to was not, or worse, that memory could now hold a different object, leading to hard to debug situations.

Flagging instances or geometries as opaque allows uninterrupted hardware intersection search and prevents invocation of the any-hit shader. Enable the use of any-hit shaders only for those geometries that need it; for example, to do alpha testing. This feature becomes available in HLSL Shader Model 6.6.

For example: On GLES3+ we can use UBOs to optimize shader parameters. At the end of the day, the use case where Vulkan and DirectX12 make the most sense is when you have hundreds of thousands of objects, which are all different (different geometry, textures, etc.), Shader abstraction. Ability to bundle shaders inside materials.

The engine should be able to render and simulate 200+ lightweight game objects -- frame-animated sprites with simple collision, no fancy physics or shaders. However, it has been designed for a fairly specific use case: tile-based pixel art platformers. (Reminder: for iOS, that means WebGL 1.0 and no WASM.) I didn't try to find out.
