Detailed Description

Runtime representation of an LM-63 Type-C photometric web.

Profiles are resampled to a fixed full-sphere grid at import time. A fixed layout makes profiles inexpensive to deduplicate and upload as one GPU structured buffer while preserving asymmetric luminaires and their roll.

Member Function Documentation

ParseLM63()

xiiResult xiiIESProfileResourceDescriptor::ParseLM63	(	xiiStringView	sSource,
		xiiStringBuilder *	pError = nullptr )

Parses an IESNA LM-63 photometric file. Type-C data and TILT=NONE are supported; invalid or unsupported inputs fail without modifying this descriptor.
