GPURenderBundleEncoder: drawIndexed() method

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is available in Web Workers.

The drawIndexed() method of the GPURenderBundleEncoder interface draws indexed primitives based on the vertex and index buffers provided by setVertexBuffer() and setIndexBuffer().

Note: This method is functionally identical to its equivalent on GPURenderPassEncoder — drawIndexed().

Syntax

js
drawIndexed(indexCount)
drawIndexed(indexCount, instanceCount)
drawIndexed(indexCount, instanceCount, firstIndex)
drawIndexed(indexCount, instanceCount, firstIndex, baseVertex)
drawIndexed(indexCount, instanceCount, firstIndex, baseVertex, firstInstance)

Parameters

indexCount

A number defining the number of indices to draw.

instanceCount Optional

A number defining the number of instances to draw. If omitted, instanceCount defaults to 1.

firstIndex Optional

A number defining the offset into the index buffer, in indices, to begin drawing from. If omitted, firstIndex defaults to 0.

baseVertex Optional

A number added to each index value before indexing into the vertex buffers. If omitted, baseVertex defaults to 0.

firstInstance Optional

A number defining the first instance to draw. If omitted, firstInstance defaults to 0.

Return value

None (undefined).

Examples

js
// …

const bundleEncoder = device.createRenderBundleEncoder(descriptor);

bundleEncoder.setPipeline(pipeline);
bundleEncoder.setBindGroup(0, sceneBindGroupForRender);
bundleEncoder.setBindGroup(1, modelBindGroup);
bundleEncoder.setVertexBuffer(0, vertexBuffer);
bundleEncoder.setIndexBuffer(indexBuffer, "uint16");
bundleEncoder.drawIndexed(indexCount);

const renderBundle = bundleEncoder.finish();
