Outputs#

The tables below list the RenderVar source names available for camera sensors, grouped by render mode. Use the sourceName value as the sourceName attribute on a RenderVar prim. Shapes are channel-last DLPack tensor shapes. Click any example image to enlarge it.

Note

The example images for non-color outputs have been remapped for easier visualization and do not represent raw output values. All output example images in the table were generated from the semantic-segmentation example.

Real-Time Path-Tracing

`sourceName`	Format	Type	Shape	Description	Example
`LdrColor`	RGBA	uint8	`(H, W, 4)`	Tone-mapped color in sRGB space. Standard “final image” output suitable for display or saving as PNG/JPEG.
`HdrColor`	RGBA	float16	`(H, W, 4)`	Linear-space HDR color preserving full scene luminance. Use for post-processing, compositing, or linear-space workflows.
`NormalSD`	XYZA	float32	`(H, W, 4)`	World-space surface normals.
`DepthSD`	Z	float32	`(H, W, 1)`	Unitless depth mapped from 1 (near clip plane) to 0 (far clip plane). Known C API issue: currently returns all zeros through C readback.
`DistanceToCameraSD`	Z	float32	`(H, W, 1)`	Euclidean distance from the camera origin to each surface point, in meters.
`DistanceToImagePlaneSD`	Z	float32	`(H, W, 1)`	Perpendicular distance from the image plane to each surface point, in meters.
`DiffuseAlbedoSD`	RGBA	uint8	`(H, W, 4)`	Diffuse surface albedo (base color without lighting).
`Camera3dPositionSD`	XYZA	float32	`(H, W, 4)`	Camera-space 3D position of each visible surface point, in scene units.
`SemanticSegmentation`	ID	uint32	`(H, W, 1)`	Per-pixel semantic ID. Decode `SemanticIdMap` to map each integer ID to its semantic label string.
`SemanticIdMap`	IdentifierMap	uint8	Buffer	Packed metadata buffer mapping semantic IDs to label strings. Each entry contains `uint32 id[4]`, label length, and label offset, followed by packed label bytes and a trailing entry count.	N/A

Path Tracing

`sourceName`	Format	Type	Shape	Description	Example
`LdrColor`	RGBA	uint8	`(H, W, 4)`	Tone-mapped color in sRGB space.
`HdrColor`	RGBA	float16	`(H, W, 4)`	Linear-space HDR color preserving full scene luminance.

Note

Additional outputs for the Path Tracing mode will be documented here as they become available.

Minimal

`sourceName`	Format	Type	Shape	Description	Example
`LdrColor`	RGBA	uint8	`(H, W, 4)`	Tone-mapped color in sRGB space.
`HdrColor`	RGBA	float16	`(H, W, 4)`	Linear-space HDR color preserving full scene luminance.

Note

Additional outputs for the Minimal mode will be documented here as they become available.
