Parameters

sourceBufferObject

Type: OIV.Inventor.DevicesSoBufferObject

The input float buffer.

targetBufferObject

Type: OIV.Inventor.DevicesSoBufferObject

The output float buffer.

kernelData

Type: SystemSingle

The kernel values.

width

Type: SystemInt32

The width of the two dimensional buffer.

height

Type: SystemInt32

The height of the two dimensional buffer.

Return Value

Returns 0 if there is no error, 1 if one of the buffers is two small.

• The data in the input buffer must contain floats.

• The function puts float values in the output buffer.

The 2D convolution performs a row convolution followed by a column convolution using the same kernel for the two passes.

To do a 2D convolution with two different 1D kernels use the row/column methods OIV.Inventor.Algorithms.SoConvolution.DoSeparateConvolutionRow(OIV.Inventor.Devices.SoBufferObject, OIV.Inventor.Devices.SoBufferObject, System.Single[], System.Int32, System.Int32) and OIV.Inventor.Algorithms.SoConvolution.DoSeparateConvolutionColumn(OIV.Inventor.Devices.SoBufferObject, OIV.Inventor.Devices.SoBufferObject, System.Single[], System.Int32, System.Int32).
