Filters

Filters collect and reorganize scene objects in your Kanzi project. You can use them to determine which scene objects to render in different render passes. After you set one or more filters or object sources, a filter collects and outputs a set of scene objects that match the requirements you define in that filter.

Use filters to adjust the rendering for the whole or parts of your Kanzi application. Set an object source for a specific render pass so that the render pass renders only objects passed to it by the object source. See Rendering.

For example, you can use filters to:

• Collect all objects in your project you want to render only once. See Using Tag Filter filters.
• Create reflections for objects. See Tutorial: Create reflections.
• Render only transparent objects. See Rendering transparent nodes.

Filters collect only 3D objects.

These filters are available in Kanzi Studio:

• Contains Property Filter collects objects that contain, or do not contain a specific property. See Using Contains Property Filter filters.
• Object Type Filter collects objects based on their type. See Using Object Type Filter filters.
• Property Is Equal Filter collects objects that contain, or do not contain a specific property the value of which matches a specific value. See Using Property Is Equal Filter filters.
• Sorting Filter either orders objects by their position on the z axis or groups them by their material type. See Using Sorting Filter filters.
• Tag Filter collects nodes that have a specific tag assigned. See Using Tag Filter filters.
