lovr.graphics.compute
This function runs a compute shader on the GPU. Compute shaders must be created with lovr.graphics.newComputeShader and they should implement the void compute(); GLSL function. Running a compute shader doesn't actually do anything, but the Shader can modify data stored in Textures or ShaderBlocks to get interesting things to happen.
When running the compute shader, you can specify the number of times to run it in 3 dimensions, which is useful to iterate over large numbers of elements like pixels or array elements.
lovr.graphics.compute(shader, x, y, z)Arguments
| Name | Type | Default | Description |
| shader | Shader | The compute shader to run. | |
| x | number | 1 | The amount of times to run in the x direction. |
| y | number | 1 | The amount of times to run in the y direction. |
| z | number | 1 | The amount of times to run in the z direction. |
Returns
Nothing
Notes
Only compute shaders created with lovr.graphics.newComputeShader can be used here.
There are GPU-specific limits on the x, y, and z values which can be queried in the compute entry of lovr.graphics.getLimits.
