The endOcclusionQuery() method of the GPURenderPassEncoder interface ends an active occlusion query previously started with beginOcclusionQuery().
The following criteria must be met when calling endOcclusionQuery(), otherwise a GPUValidationError is generated and the GPURenderPassEncoder becomes invalid:
- An occlusion query is active for this render pass (i.e. via a previous
beginOcclusionQuery() call).
const querySet = device.createQuerySet({
type: "occlusion",
count: 32,
});
const renderPassDescriptor = {
colorAttachments: [
{
clearValue: clearColor,
loadOp: "clear",
storeOp: "store",
view: context.getCurrentTexture().createView(),
},
],
occlusionQuerySet: querySet,
};
const passEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);
passEncoder.beginOcclusionQuery(0);
passEncoder.setPipeline(renderPipeline);
passEncoder.setVertexBuffer(0, vertexBuffer);
passEncoder.draw(3);
passEncoder.endOcclusionQuery();
