Code Samples

GeeXLab Code Samples - Basics

» Texture - JPG image This example shows how to load a JPG image.

» Texture - Video AVI This example shows how to load an animated texture (AVI file).

» Built-in Meshes This example shows how to use some of the built-in meshes (here a sphere and a torus) and display vertices normals.

» Skybox This example shows how to load a skybox (simple way and with Python).

» HUD This example shows how to use HUD (Head Up Display) and play with color blending factors.

GeeXLab Code Samples - Direct Model Loading

» 3DS Format - Cube This example shows how to load a textured model from a 3DS file. There is no dynamic lighting.

» W4K Format - Plane This example shows how to load a multi-textured model from a W4K file. W4K format is generated with the W4K Mesh Exporter for 3ds Max.

» OBJ Format - Cube This example shows how to load a model from an OBJ (Alias Wavefront) file.

» DirectX Format - Tiger This example shows how to load a model from a DirectX file.

» Collada Format - Car This example shows how to load a model from a Collada file.

GeeXLab Code Samples - Python

» Hello World! This example shows how to use Python scripts. This is the famous Hello World of programming languages.

» Texture Viewer This example shows how to use drag n drop scripts (Python scripting) to load and display several texture files at the same time.

» Shared Variables This example shows how to use the shared variables to share data between Python and Lua scripts.

» NetworkX This example shows how to use the NetworkX library. More information HERE. You have to install the NetworkX library before loading this demo.

» Post Direct Rendering This example shows how to use the post direct rendering scripts to have a full control on the rendering.

» PyOpenGL This example shows how to use the PyOpenGL library with post direct rendering scripts. More information HERE. You have to install the PyOpenGL library before loading this demo

GeeXLab Code Samples - Lua

» 3D Curve This example shows how to create a curve object and render a 3D curve (here a sine).

» Render to texture This example shows how to do render to texture (RTT).

» Motion Path Editor This example shows a very simple motion path editor.

» Hierarchy This example shows how to setup a hierarchy.

» Draw Line This example shows how to draw a line using a line object and without a line object in immediate mode (post direct rendering).

» Model Cloning This example shows how to clone a model. The model can be seen as a template and you can create new model by cloning the template. In the demo, just press the SPACE key to clone the model.

GeeXLab Code Samples - GLSL Shaders

» Point Light - Phong Lighting This example shows how to implement a Phong shader in GLSL.

» Simple Bump Mapping This example shows how to do bump mapping with normal map and a GLSL shader.

GeeXLab Code Samples - Post Processing

» Bloom PostFX This example shows how to use post processing filters to create a bloom effect.

» Negative PostFX This example shows how to create a negative post processing filter that simply reverses colors.

GeeXLab Code Samples - Shadows

» Shadow Volume This example shows how to simulate soft shadows with shadow volumes and several light sources.

» Shadow Mapping This example shows how to use the shadow mapping to create nice soft shadows.

GeeXLab Code Samples - Instancing

» Software Mesh Instancing This example shows how to do software mesh instancing in Lua.

» Software Mesh Instancing - Spirale This example shows how to do software mesh instancing in a simple hierarchy.

GeeXLab Code Samples - NVIDIA PhysX

» Simple PhysX demo This example shows how use NVIDIA PhysX with the drop of a simple cube. You have to install the latest PhysX System Software before running this demo.

» Revolute joints This example shows how use revolute and breakable joints. You have to install the latest PhysX System Software before running this demo.

GeeXLab Code Samples - Particle System

» Point Emitter This example shows how use a simple point emitter.

GeeXLab Code Samples - Audio / Sound

» MP3 File This example shows how to load and play a MP3 file.

» 3D Sound This example shows how to load a sound file and use 3D sound capabilities. The source of sound is attached to a gizmo moving on the motion path.

» Sound Phaser This example shows how start sound playing when you want. Each time you press the SPACE key, the mesh sphere polygon mode is changed (LINE / SOLID) and a sound (phaser) is played.

GeeXLab Code Samples - Font

» 2D Bitmap fonts This example shows how to use 2D fonts created from bitmap files. Bitmap files have been created with Bitmap Font Generator. This program will allow you to generate bitmap fonts from TrueType fonts.

» 3D fonts This example shows how to use 3D fonts.
