final func drawListSetPushConstant(drawList: Int, buffer: PackedByteArray, sizeBytes: UInt32) Sets the push constant data to buffer for the specified drawList. The shader determines how this binary data is used. The buffer’s size in bytes must also be specified in sizeBytes (this can be obtained by calling the size method on the passed buffer).

final func freeRid(_ rid: RID) Tries to free an object in the RenderingDevice. To avoid memory leaks, this should be called after using an object as memory management does not occur automatically when using RenderingDevice directly.

This is used to cache shader files on disk, which avoids shader recompilations on subsequent engine runs. This UUID varies depending on the graphics card model, but also the driver version. Therefore, updating graphics drivers will invalidate the shader cache.
final func getDeviceVendorName() -> String Returns the vendor of the video adapter (e.g. “NVIDIA Corporation”). Equivalent to getVideoAdapterVendor. See also getDeviceName.
final func getDriverResource(_ resource: RenderingDevice.DriverResource, rid: RID, index: UInt) -> UInt Returns the unique identifier of the driver resource for the specified rid.

See also shaderCompileSpirvFromSource(shaderSource:allowCache:).

Compiles a SPIR-V from the shader source code in shaderSource and returns the SPIR-V as a RDShaderSPIRV.

final func textureClear(texture: RID, color: Color, baseMipmap: UInt32, mipmapCount: UInt32, baseLayer: UInt32, layerCount: UInt32) -> GodotError Clears the specified texture by replacing all of its pixels with the specified color. baseMipmap and mipmapCount determine which mipmaps of the texture are affected by this clear operation, while baseLayer and layerCount determine which layers of a 3D texture (or texture array) are affected by this clear operation. For 2D textures (which only have one layer by design), baseLayer must be 0 and layerCount must be 1.

The number of included mipmaps from the original texture can be controlled using the mipmaps parameter. Only relevant for textures with multiple layers, such as 3D textures, texture arrays and cubemaps. For single-layer textures, use textureCreateShared(view:withTexture:)
final func textureGetData(texture: RID, layer: UInt32) -> PackedByteArray Returns the texture data for the specified layer as raw binary data. For 2D textures (which only have one layer), layer must be 0.

final func textureUpdate(texture: RID, layer: UInt32, data: PackedByteArray) -> GodotError Updates texture data with new data, replacing the previous data in place. The updated texture data must have the same dimensions and format. For 2D textures (which only have one layer), layer must be 0. Returns @GlobalScope.OK if the update was successful, @GlobalScope.ERR_INVALID_PARAMETER otherwise.
