GPURenderBundleEncoder: drawIndexed() method

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

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();
