OpenGL computes surface shading by evaluating lighting equations at polygon vertices.

The most general form of the lighting equation uses both the vertex position and a vector that is normal to the object’s surface at that position; this is called the normal vector. Ideally, these normal vectors are captured or computed with the original model data, but in practice there are many models that do not include normal vectors.

OpenGL : Interaction

The model for interpretation of OpenGL commands is client-server. An application (the client) issues commands, which are interpreted and processed by OpenGL (the server). In this sense, OpenGL is network-transparent. A server can maintain several GL contexts, each of which is an encapsulated GL state. A client can connect to any one of these contexts. The required network protocol can be implemented by augmenting an already existing protocol or by using an independent protocol. No OpenGL commands are provided for obtaining user input.

This is a basic course for new developers to introduced Creo customization using VB API. Creo is flagship product of PTC and one of the leading CAD product of MCAD industry. Creo can be customized using VB, WebLink, Jlink and ProToolkit. First three interfaces are free of cost and made available to user along with main product. However Pro/Toolkit is substantially costly product however has highest number of API in C to customize Creo.
