v1.0.1

• Package dependencies updated.

• Add support for Julia 1.7.

v1.0.0

First stable version.

⚠⚠⚠ BREAKING CHANGES ⚠⚠⚠

• CLI demo command is removed in favor of the command render: this command takes a SceneLang script (see below) as input and generates an hdr image (and optionally the corrispective ldr image).

New package features

• Add SceneLang support (#27).

New CLI tool features

• Add docs command to show documentation informations.

• Add --luminosity option in tonemapping command (#30).

Improvements

• Improve documentation.

v0.2.1

• Improve documentation.

v0.2.0

⚠⚠⚠ BREAKING CHANGES ⚠⚠⚠

• Removed type parameters from most structs. All floating points calculations are now performed on Float32. This provides a significant speedup. All code specifying type parameters will be broken from now on (#23).

• Renamed the following functions:

  • average_luminosity(image::HdrImage; δ::Float32) -> luminosity(image::HdrImage; δ::Float32)

  • normalize_image(image::HdrImage, α::Float32; luminosity::Float32) -> normalize(image::HdrImage, α::Float32; luminosity::Float32)

  • clamp_image(image::HdrImage) -> clamp(image::HdrImage)

New package features

• Add PointLightRenderer renderer with relative PointLight composite type and Lights alias (#20)

• Add PathTracer renderer (#20).

• Add the implementation of an OrthoNormal Basis (ONB) creation algorithm based on Duff et al. 2017 (#20).

• Add a PCG-family Random Number Generator (RNG) based on O'Neill 2014 as a Random.AbstractRNG (#18).

• API now includes high-level functions for basic scene rendering, image tonemapping, and a demo function (see user_utils.jl).

• Add OnOffRenderer and FlatRenderer renderers to apply to the scene (#17).

• Add the implementation of materials for our shapes, describing both the BRDF and radiance of the shape interface (#17).

• Add the implementation of some basic shapes, such as spheres (#11).

• Add the implementation of an image tracer, needed to capture light from a scene (#3).

• Add geometry implementation, needed to compute a 3D scene (#2).

New CLI tool features

• Add demo command to show a demo rendering (#13).

v0.1.0

First Release: Basic PFM to LDR image conversion

This version of the package implements:

• Loading of a file in PFM format using the package ImagePFM;
• Tone mapping;
• Gamma correction
• Saving to file formats supported by the package FileIO.

Consult the README.md file for usage through CLI.
