Working through examples in the OpenGL Red Book (in Go)

Go Red Book

Examples from OpenGL Programming Guide, Eighth Edition ported to the Go Programming Language.

In addition to being ported from C++ to Go, the following additional changes have been made:

• code initializing OpenGL/creating windows, has been moved to the utils package in order to reduce duplicating code that does not change between examples.
• where appropriate the examples have been modified to have a more consistent flow from one example to the next. This involves some of the following:
  • using the same style in all shaders (not usually a problem with Go).
  • consistent naming of variables across all examples. If it is called "MCvertex" in one example, it should be called "MCvertex" in all examples.
• any modifications specific to the examples, should be documented in the "Notes" section of the example.

Chapter 1: Introduction to OpenGL

• Triangles

Chapter 3: Drawing with OpenGL

• Draw Commands
• Primitive Restart

Chapter 4: Color, Pixels, and Framebuffers

• Gouraud

Running Examples

First see "Installing Examples" if you have not done so already.

$ cd $GOPATH/src/github.com/hurricanerix/gorb
$ make
mkdir -p bin
go build -o bin/ch01-triangles 01/triangles/main.go
go build -o bin/ch03-drawcommands 03/drawcommands/main.go
...
$ ./ch01-triagnles
...
