Functions
-
allocateUTF8(String str)
→ JSString
-
-
ccall(JSString name, JSString returnType, JSArray<JSAny?> argTypes, JSArray<JSAny?> args, JSObject opts)
→ JSPromise<JSAny?>
-
-
ensureMinigpuModuleLoaded()
→ Future<void>
-
Load (or adopt) the minigpu wasm module once. Safe to await repeatedly.
Throws on fetch/instantiation failure — callers surface that as "no GPU
on this platform" rather than a silent hang.
-
mgpuCreateBuffer(int elements, int dataType)
→ MGPUBuffer
-
-
mgpuCreateComputeShader()
→ MGPUComputeShader
-
-
mgpuDestroyBuffer(MGPUBuffer buffer)
→ void
-
-
mgpuDestroyComputeShader(MGPUComputeShader shader)
→ void
-
-
mgpuDestroyContext()
→ Future<void>
-
-
mgpuDispatch(MGPUComputeShader shader, int groupsX, int groupsY, int groupsZ)
→ Future<void>
-
-
mgpuGetWGPUBufferHandle(MGPUBuffer buf)
→ int
-
Returns the Emscripten integer handle for a WGPUBuffer inside
buf.
Pass to getWebGpuJsObject from webgpu_interop.dart to get the JS GPUBuffer.
-
mgpuGetWGPUDeviceHandle()
→ int
-
Returns the Emscripten integer handle for the WGPUDevice.
Pass to getWebGpuJsObject from webgpu_interop.dart to get the JS GPUDevice.
-
mgpuHasKernel(MGPUComputeShader shader)
→ bool
-
-
mgpuImportExternalTexture(JSAny videoFrame)
→ JSObject?
-
Import a
VideoFrame (or HTMLVideoElement) as a GPUExternalTexture.
-
mgpuInitializeContext()
→ Future<void>
-
-
mgpuLandExternalTexture({required JSObject externalTexture, required int dstBufferHandle, required int width, required int height, required int downscale})
→ bool
-
Run the external-texture landing pass:
externalTexture -> packed RGBA8
array<u32> in the buffer behind dstBufferHandle, the same destination
layout the native D3D11 path writes.
-
mgpuLoadKernel(MGPUComputeShader shader, String kernelString)
→ void
-
-
mgpuReadAsyncDouble(MGPUBuffer buffer, Float64List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncFloat(MGPUBuffer buffer, Float32List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncInt16(MGPUBuffer buffer, Int16List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncInt32(MGPUBuffer buffer, Int32List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncInt64(MGPUBuffer buffer, TypedData outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncInt8(MGPUBuffer buffer, Int8List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
Asynchronous read functions for multiple types.
Each function allocates native memory, calls ccall with async:true,
then copies the data from the WebAssembly heap into the given Dart TypedData.
-
mgpuReadAsyncUint16(MGPUBuffer buffer, Uint16List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncUint32(MGPUBuffer buffer, Uint32List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncUint64(MGPUBuffer buffer, TypedData outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuReadAsyncUint8(MGPUBuffer buffer, Uint8List outputData, {int readElements = 0, int elementOffset = 0})
→ Future<void>
-
-
mgpuSetBuffer(MGPUComputeShader shader, int tag, MGPUBuffer buffer)
→ void
-
-
mgpuSetLogLevel(int level)
→ void
-
Minimum native log verbosity (0=DEBUG 1=INFO 2=WARN 3=ERROR, -1 silences
all). The wasm default is INFO, which narrates ~7 buffer ops per encoded
frame straight onto the browser console via stderr
printChar. Callable
only once the module is loaded — MinigpuWeb stages the level and applies
it right after ensureMinigpuModuleLoaded, before context init, so even
the adapter/device bring-up logs honor it.

mgpuWriteDouble(MGPUBuffer buffer, Float64List inputData, int size)
→ void
-

mgpuWriteFloat(MGPUBuffer buffer, Float32List inputData, int size)
→ Future<void>
