04.2 Creating a 3D image

CreatingImage3D This example demonstrates how to create a new 3D image containing data from a buffer.

DESCRIPTION:

First this example shows how to fill an SoCpuBufferObject with synthetic values that would represent a bright 3D bar on a gray background.

Then this buffer is set in an SoMemoryDataAdapter that corresponds to a 3D 256x256x32 image.

At least a simple scene graph is built and the image is displayed in a viewer with as a volume rendering.

NOTE:

• This example shows how to assign synthetic data to an SoMemoryDataAdapter. It could be easily used to assign a buffer from an acquisition or an owner image format in an SoMemoryDataAdapter
• Then the SoMemoryDataAdapter object can be used as input for most of ImageViz engines.
