        geometrySourceWithBuffer:semantic:vectorCount:floatComponents:componentsPerVector:bytesPerComponent:dataOffset:dataStride: Creates and returns a geometry source from the given data and parameters. Attempting to modify the Metal buffer outside the SCNSceneRenderer delegate callbacks is undefined. The typical usage it to modify the MTLBuffer within the willRenderScene callback, using a compute kernel or a vertex function in the user own command buffer. So something like: - (void)renderer:(id )aRenderer willRenderScene:(SCNScene *)scene atTime:(NSTimeInterval)time { // ask for a new command buffer id myCommandBuffer = [aRenderer.commandQueue commandBuffer]; // get a compute command encoder id myComputeCommandEncoder = [myCommandBuffer computeCommandEncoder]; // configure the compute command encoder's pipeline state, buffer inputs etc... //... // dispatch the [myComputeCommandEncoder dispatchThreadgroups:numberOfWorkingGroups threadsPerThreadgroup:numberOfThreads]; [myComputeCommandEncoder endEncoding]; [myCommandBuffer commit]; }
        Parameters:
        buffer - A Metal buffer.
        vertexFormat - The vertex format.
        semantic - The semantic of the geometry source.
        vertexCount - The number of vertex.
        offset - The offset from the beginning of the data. In bytes.
        stride - The number of bytes from a vector to the next one in the data.
