The GPU api provides interaction with and is part of the CCGPU peripheral.
Arguments surrounded with square brackets are optional.
These methods can be used in any ComputerCraft program if the CCGPU api is installed.
|gpu.getID([side])||Returns the ID of the GPU on the given side.|
|gpu.setRenderCode([side], renderCode)||Sets the gpu rendering code, this code is ran every frame.|
|gpu.loadRenderCode([side], filePath)||Equivalent to setting the render code, but loads it from a file.|
|gpu.setVar([side], name, value)||coming soon|
|gpu.getLatestError([side])||Returns the last error that has been thrown by Lua in your render code.|
These methods can be used in render code when set using gpu.setRenderCode.
|gpuCreateBuffer(width, height)||Coming soon|
|gpuClearBuffer()||Clear the currently bound buffer.|
|gpuBindOutputBuffer(id)||Start drawing to a different buffer. (Set this to a certain monitor ID to draw to it.)|
These methods are part of OpenGL and can only be used in render code when set using gpu.setRenderCode.
|glBegin(mode)||Begins drawing something (Begins GL scope). mode should be a constant like GL_QUADS or GL_TRIANGLES. You must invoke this function before setting vertices for the shape.|
|glEnd()||Invoke this when you've set all your vertices (Ends GL scope).|
|glTexCoord2f(x, y)||Coming soon|
|glVertex2f(x, y)||Use this between glBegin(mode) and glEnd() to set a 2D vertex.|
|glVertex3f(x, y, z)||Use this between glBegin(mode) and glEnd() to set a 3D vertex.|
|glColor3f(red, green, blue)||Use this between glBegin(mode) and glEnd() to set the color.|
|glColor4f(red, green, blue, alpha)||Use this between glBegin(mode) and glEnd() to set the color with alpha (opacity).|
These constants are part of OpenGL and can only be used in render code when set using gpu.setRenderCode.
|GL_QUADS||Constant for drawing a quadrilateral.|
|GL_TRIANGLES||Constant for drawing a triangle.|
|GL_POINTS||Constant for drawing a pixel at each vertex given.|
Although some constants are not yet included in the API, they can already be used. Therefore you have to pass in the value which is associated with the constant.
|Associated value||Constant name||Description|
|1||GL_LINES||Value for drawing a line.|
|2||GL_LINE_LOOP||Value for drawing a line loop.|
|3||GL_LINE_STRIP||Value for drawing a line strip.|
|5||GL_TRIANGLE_STRIP||Value for drawing a triangle strip.|
|6||GL_TRIANGLE_FAN||Value for drawing a triangle fan.|
|8||GL_QUAD_STRIP||Value for drawing a quad strip.|
|9||GL_POLYGON||Value for drawing a convex polygon.|
