• Press WASD to move the camera
• Press Q/E to descend or ascend
• Hold RMB to pan the camera

• PlyLoader loads vertex and face elements from a .ply file
• Model represents a model's geometry imported from PlyLoader
• Revise shader if necessary

• Transform vertex from CUDA kernel
• Transform vertex from OpenMP

• Let the vertex shader transform coordinates from one space to another
• Each Geometry has its own Local space
• A Transform maps the object's coordinates to World space
• A Camera transforms the entire scene into its View space
• Subsequently, the camera projects the view into 2-dimensional Clip space

• A Geometry has a list of vertex and a shader used to draw itself
• A Transform defines the position and rotation of the object

• Vertex shader
• Fragment shader

Use GLSL shaders to draw a triangle

• Camera class holds a pointer to view matrix whose memory isn't released upon destructor call
• Same applies to Geometry class

The bottom line is that some objects do not have the normal vectors that diffuse lighting depends on.
We apply cross product between two vectors in a mesh to compute its normal vector.
