A 3D renderering engine, written as a tool to drive my understanding of OpenGL and 3d graphics in general.
####Requirements
- C++11
- cmake - build tool
- OpenGL, glew
- SDL2 - Window creation, input handling
- SDL2Image - Reading png/jpeg textures
- glm - vector maths
- Assimp - Loading models
####Building
To perform an out-of-source build, first navigate to the root directory and then run the following commands.
mkdir build
cd build
cmake -DGAME=<game> ..
make
where <game> is one of the test scenes in the game folder (see below). Then rendering can be started by running the created 3dengine binary.
####Example scenes
There are a few example scenes in the game folder that show different aspects of the rendering engine.
All scenes render in a 1280x720 window, with a frame cap of 240fps. Frame rate is output to stdout. In all scenes the camera can be controlled with the familiar w a s d controls. space raises the camera and ctrl lowers it. Clicking the screen will allow the mouse to be captured for mouselook. esc will release the mouse. In some scenes there is a object that can be controlled independently from the camera in order to test various lighting behaviours. This object can be controlled with i j k l for movement, o to raise, p to lower and the arrow keys for rotation.
| Name | Description |
|---|---|
showcase |
A mix of different objects to show a mix of features of the engine. |
cubemap_test |
Testing of the skybox via cubemaps. |
normal_test |
Testing of normal mapping. Cubes on the left have no normal maps whereas the ones on the right do. Small cube can be moved to position light. |
reflection_test |
Testing of realtime recursive reflection. Cube mirror can be moved. |
shadow_test |
Testing of realtime directionallight shadows. |
shadow_test2 |
Testing of realtime spotlight shadows. Light can be moved/rotated. (Note player has a model that also casts a shadow.) |
texture_test |
Test of various textures wrapped on a cube and on the "Suzanne" monkey head model. |
