Code Sample 78  

Shows a torus lit by an OMNI red light. It shows how to use the light's diffuse component and how to optimize a mesh.

Keywords: scene - camera - mesh - light - diffuse - optimize - material - attach_material - spin_values - torus




Code Sample 72  

Shows how to use several SPOT lights. Shows the importance of the global ambient light.

Keywords: scene - global_ambient_light - camera - light - SPOT - spot_angle - orientation - add_texture - mesh - plane




Code Sample 77  

Outlines the impact of the material ambient component.

Keywords: scene - camera - light - material - ambient_reflection_factor - diffuse_reflection_factor - specular_reflection_factor - orientation - pitch - font - text_3d - mesh




Code Sample 69  

Shows the effects of tuning the lights' parameters to get a realistic rendering. The code sample shows how to accurately apply the light's attenuation (the linear, the constant and the quadratic attenuation) to progressively decrease the light's intensity as the distance grows. It shows the importance of the mesh density for getting high quality specular reflexion, as well as the use of an optimization method and the vertex buffer object (vbo) to speed up the rendering of meshes featuring static polygones (detailed explanations about these techniques are available in the Lighting and material tutor).

Keywords: scene - camera - light - linear_att - constant_att - quadratic_att - material - ambient_reflection_factor - diffuse_reflection_factor - specular_reflection_factor - mesh - optimize - plane - torus - improve_specular_highlights - use_vbo - polygon_mode




Code Sample 52  

Shows a simple scene with volumic shadows. The code shows how to render shadows of several objects within a single 3ds format scene. It shows how to move an object (the light) with a very simple LUA script.

Keywords: scene - camera - light - texture - material - mesh - plane - model - shadow_caster - script - run_mode




Code Sample 70  

This code features volumic shadows like in code sample 52, but with a more sofisticated 3D model. It shows how to move a light in LUA scripting.

Keywords: scene - camera - light - texture - material - script - primitive - mesh - plane - model - shadow_caster
