Detailed Description

Loader for EXR (OpenEXR) image files.

Provides functionality to load EXR image files, with support for loading headers separately (useful for ECS systems) and loading full image data. Converts planar EXR channel data to interleaved format compatible with glTF/OpenGL.

Member Function Documentation

◆ load()

tinygltf::Image Engine::Assets::Textures::ExrLoader::load ( const std::filesystem::path & filename )

Load a complete EXR image file.

Loads both header and pixel data from an EXR file and converts it to a tinygltf::Image format. The image data is interleaved (RGBA) from the planar format used by EXR files. Channel order is converted from EXR's BGR to RGB for OpenGL compatibility.

Parameters

filename Path to the EXR file to load

Returns: tinygltf::Image containing the loaded image data

Return values

Empty image if loading fails

◆ loadHeader()

ExrHeader Engine::Assets::Textures::ExrLoader::loadHeader ( std::filesystem::path path )

nodiscard

Load only the header information from an EXR file.

Parses and extracts header information without loading pixel data. Useful for inspecting file properties before loading, or for use with ECS systems that need header data as components.
