paragraph: "Clip coordinates are a little different from regular positions. A position in 3D space has 3 coordinates. A position in clip space has four coordinates. The first three are the usual X, Y, Z positions; the fourth is called W. This last coordinate actually defines the extents of clip space is for this vertex." <-- SENTENCE W/ ISSUE suggestion : This last coordinate actually defines what the extents of the clip space are for this vertex.

paragraph: "The set of reference colors is called a colorspace. The most common color space a screen is linear RGB, where the reference colors are Red, Green and Blue. <-- SENTENCE W/ ISSUE Printed works tend to use CMYK (Cyan, Magenta, Yellow, Black). Since we're dealing with rendering to a screen, and because OpenGL requires it, we will use the linear RGB colorspace." suggestion : The most common color space for a screen is linear RGB, where the reference colors are Red, Green and Blue.

paragraph: "So a pixel in OpenGL is defined as 3 values on the range [0, 1] that represent a color in the linear RGB colorspace. By combining different intensities of this 3 colors, we can generate millions of different color shades. <-- SENTENCE W/ ISSUE This will get extended slightly, as we deal with transparency later."" suggestion : By combining different intensities of theese 3 colors, we can generate millions of diffrent color shades.
