raymarchRender3D
RayTK
v0.42

Renders a scene using 3D raymarching.

Parameters

Name Description Regular Handling Read-Only Handling
Resolution

Rendering resolution
Anti Alias

Number of antialiasing steps. Increasing this improves render quality but can be costly.

 Baked Baked
Use Render Depth

Whether to use the provided Render TOP for a base depth.

 Runtime Baked
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.

 Semi-Baked Semi-Baked
Surface Distance

Minimum surface distance. Smaller values increase accuracy at the cost of performance.

 Semi-Baked Semi-Baked
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.

 Runtime Baked
Near Hit Range

Advanced feature, not ready for use.

 Runtime Baked
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.

 Runtime Baked
Limit Box Maximum

Maximum bounds of the scene limit box.

 Runtime Baked
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.
