Render To Texture

The Render To Texture Behavior in CopperCube provides a flexible and dynamic way to project a camera view onto a model. It is configurable through XML parameters, allowing users to control rendering frequency, target parameters, and overall customization of the rendering process.

1. Camera and Model Specification:
   • Utilize the XML parameters to define the camera (scene node) and the target model (scene node) for rendering.
2. Material Index and Resolution Control:
   • Fine-tune the rendering process by specifying the material index on the target model and setting the resolution of the rendered texture.
3. Time-Based Rendering Cycle:
   • The behavior employs a time-based approach, allowing users to control the frequency of rendering through the 'timeMs' parameter.

Workflow:

1. Initialization:
   • The behavior initializes by registering the rendering function (drawScreenFunc) to be executed on each frame.
2. Rendering Cycle:
   • On each frame, the behavior checks if it's time to render based on the specified interval.
   • If rendering is due, the ccbRenderToTexture function is invoked, projecting the camera view onto the specified model.
3. Scheduling:
   • The end time for the rendering cycle is updated, ensuring the next rendering event is scheduled according to the specified time interval.
