Write a program to draw a triangle in computer graphics

So this triangle should take most of the screen.

The second parameter specifies the number of values for that input, which is the same as the number of components of the vec. For example, if one triangle is obscured by another triangle, the fragment of the closer triangle should end up on the screen.

Besides, the triangle had three line segments… At this point, I left my students for about an hour, reading my code was less valuable than comparing their code with mine. Clipping discards all fragments that are outside your view, increasing performance.

As you can see, the graphics pipeline contains a large number of sections that each handle one specific part of converting your vertex data to a fully rendered pixel.

Notice that just as buffers, shaders are not directly accessible : we just have an ID. It all begins with the vertices, these are the points from which shapes like triangles will later be constructed. The graphics pipeline covers all of the steps that follow each other up on processing the input data to get to the final output image. This is why it's possible to decide per application what attributes each vertex should have. Putting it all together This will be another long tutorial. Adding some more colors Although uniforms have their place, color is something we'd rather like to specify per corner of the triangle! The next step is to upload this vertex data to the graphics card. No spam. It's up to you to write the code for computing this color from vertex colors, texture coordinates and any other data coming from the vertex shader. The outColor variable uses the type vec4, because each color consists of a red, green, blue and alpha component. Common types are f float , d double and i integer. Finally, the end result is composed from all these shape fragments by blending them together and performing depth and stencil testing. On a side note, notice that you can move your hand freely : your X, Y and Z will be moving, too.

This statement makes the VBO we just created the active array buffer. Finally, the end result is composed from all these shape fragments by blending them together and performing depth and stencil testing. Each vertex can have numerous attributes : A position, one or several colours, one or several texture coordinates, lots of other things.
