initializeStaticResources static method
Loads the bundled BRDF lookup texture used by the PBR fragment shader's split-sum specular IBL.
Called by the Scene constructor; rendering is gated on the returned Future completing. The same future is reused on subsequent calls.
Implementation
static Future<void> initializeStaticResources() {
return gpuTextureFromAsset(
'packages/flutter_scene/assets/ibl_brdf_lut.png',
).then((gpu.Texture value) {
_brdfLutTexture = value;
});
}
