scala-ray README ================ A basic raytracer written in Scala. Author: Daniel Lichtenberger (daniel.lichtenberger@gmail.com) License: GPL3 (see GPL.txt) Platform: Scala 2.8 Installation ============ * Install Java and Maven 2 * $ cd scala-ray * $ mvn package * $ java -jar target/scala-ray-1.0-SNAPSHOT.jar will print the command line options. Features ======== Done: * Basic primitives (Planes, Spheres) * Point and area light sources * Textures * Soft shadows (jittered lightsource sampling) * Supersampling with optional edge detection (LOW quality setting) Possible TODOs: * A scene description language (the example scenes are hard-coded in Scala) * BSPs for more complex scenes * Fix embarrassing command-line handling * Swing preview window * Build: migrate to sbt for incremental compiles * Performance: switch back to mutable vector math DISCLAIMER ========== This is really a personal education project. Don't expect anything new or useful here. Performance is so-so, I fell back to Java-ish code for most hot loops (which is almost everywhere except in the scene setup). Also, the JVM is probably not the ideal platform for such a project to begin with (no value objects, boxing, no SIMD, range checks, etc.). Coding ====== The project follows the standard Maven project layout: the sources are in src/main/scala, the tests under src/test/scala. The example scenes can be found in src/main/scala/net/lichtd/ray/ExampleScenes.scala. Some example images can be found in the pics/ folder.
