Gleam
is not responsible for OpenGL context creation. Instead, it is a wrapper that unifies OpenGL and OpenGles APIs.
Users are expected to use other libraries to create an OpenGL context and then wrap with Gleam
.
Let's see an example:
"users creates a context as she wishes"
context := self createContext.
"a context must be valid and be made current"
context makeCurrent.
"Gleam wraps OpenGL functions by loading OpenGL functions by their name"
gl := GtGleamGL loadGl: [ :aSymbol | context getProcAddress: aSymbol ].
"Now we are ready to draw"
gl clear_color: Color red.
gl clear: gl GL_COLOR_BUFFER_BIT.
"once rendering is completed swap buffers to display on the screen"
context swapBuffers.
