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().
js
drawIndexed(indexCount)
drawIndexed(indexCount, instanceCount)
drawIndexed(indexCount, instanceCount, firstIndex)
drawIndexed(indexCount, instanceCount, firstIndex, baseVertex)
drawIndexed(indexCount, instanceCount, firstIndex, baseVertex, firstInstance)
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.
None (Undefined).
