04.1 Creating a 2D image

CreatingImage2D This example demonstrates how to create a new 2D image containing data from a buffer.

DESCRIPTION:

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

Then this buffer is set in an SoMemoryDataAdapter that corresponds to a 2D 512x512 image.

At least a simple scene graph is built and the image is displayed as an orthoslice in a viewer.

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.
