Detailed Description

Use the Blit Render Pass to blit one or more textures to the screen of the current rendering context using a material.

After the blit operation, a Blit Render Pass passes the control to its descendants and then further to its siblings and parent.

Use the Blit Render Pass to show the result of other render passes. For example, to show the result of a Composition Target Render Pass, in the Blit Render Pass bind one of the texture properties (Texture0Property, Texture1Property, Texture2Property, or Texture3Property) to the render target texture that the Composition Target Render Pass creates:

        // To show the result of a Composition Target Render Pass, in the Blit Render Pass bind the Texture0Property
        // to a Composition Target Render Pass. In this example, the "Composition Target Render Pass" is a sibling
        // to the Blit Render Pass.
        blitRenderPass->addTextureBinding(BlitRenderPass::Texture0Property, "../Composition Target Render Pass");

Kanzi Studio uses a default blit material named "DefaultBlitMaterial" which is in the resource dictionary of the Screen node. This default blit material uses only the Texture0Property and its purpose is to show the result of a CompositionTargetRenderPass.

If you use your own materials in a Blit Render Pass, to ensure ease of use in Kanzi Studio projects, use the Blit Render Pass default texture properties.
