RayTK

v0.36

Renders a scene using 3D raymarching.

Parameters

• Resolution: Rendering resolution
• Anti Alias: Number of antialiasing steps. Increasing this improves render quality but can be costly.
• Use Render Depth: Whether to use the provided Render TOP for a base depth.
• Overlay Render: Whether to mix the provided Render TOP with the scene using depth.
• Render TOP: Connect a Render TOP to mix with the scene based on depth.
• Max Steps: Maximum number of marching steps.
• Surface Distance: Minimum surface distance. Smaller values increase accuracy at the cost of performance.
• Max Distance: Maximum distance. Rays that don't hit anything will stop at this distance. If this is too high, rays that don't hit anything will continue for a long time, causing a performance drain.
• Near Hit Range: Advanced feature, not ready for use.
• Time Reference Operator: COMP to use to determine the time. Only relevant if using a time field.
• Use Limit Box: Whether to limit the space of the scene to a box, for performance improvements.
• Limit Box Minimum: Minimum bounds of the scene limit box.
• Limit Box Maximum: Maximum bounds of the scene limit box.
• Shader Builder Config: Advanced configuration for the shader.
• Enable Depth Output: Enables the depth output buffer.
• Enable SDF Output: Enables the SDF data output buffer.
• Enable World Pos Output: Enables the world xyz position output buffer.
• Enable Normal Output: Enables the surface normals output buffer.
• Enable Ray Direction Output: Enables the ray direction output buffer.
• Enable Ray Origin Output: Enables the ray origin (camera position) output buffer.
• Enable Orbit Trap Output: Enables the fractal orbit trap output buffer (only supported for certain SDFs).
• Enable Near Hit Output: Enables near hit output which shows where rays got close to hitting surfaces.
• Enable Step Output: Enables step count output which shows how many steps each ray took while marching through the scene.
• Enable Iteration Output: Advance feature, not ready for use.
• Enable Object Id Output: Enables object id output which shows id values assigned using `injectObjectId`.
• Enable Debug Output: Advance feature, not ready for use.
