@FastNative
public final external @NonNull GPUComputePassEncoder beginComputePass(GPUComputePassDescriptor descriptor)

Begins recording a compute pass.

Parameters

The descriptor for the compute pass.
Returns
@NonNull GPUComputePassEncoder

A compute pass encoder.

beginRenderPass

Added in 1.0.0-alpha05
@FastNative
public final external @NonNull GPURenderPassEncoder beginRenderPass(@NonNull GPURenderPassDescriptor descriptor)

Begins recording a render pass.

Parameters
@NonNull GPURenderPassDescriptor descriptor

The descriptor for the render pass.

@NonNull GPURenderPassEncoder

A render pass encoder.

clearBuffer

Added in 1.0.0-alpha05
@FastNative
public final external void clearBuffer(@NonNull GPUBuffer buffer, long offset, long size)

Fills a buffer with zeros.

Parameters
@NonNull GPUBuffer buffer

The buffer to clear.
long offset

The offset in the buffer.
long size

The number of bytes to clear.

close

Added in 1.0.0-alpha05
public external void close()

Decrements the reference count of the object and frees resources when the count reaches zero.

This is the standard way to manage object lifetimes and should be used in use blocks. After calling this, the object is no longer usable.

copyBufferToBuffer

)

Copies data from one buffer to another.

Parameters
@NonNull GPUBuffer source

The source buffer.
long sourceOffset

The offset in the source buffer.
@NonNull GPUBuffer destination

The destination buffer.
long destinationOffset

The offset in the destination buffer.
