So, for example, let's assume that you render your 320x240 texture on a 320x240 quad. Then the bottom-left pixel (0,0) will actually be sampled at screen-coordinates (.5,.5). You normalize it by dividing by (320,240), but then OpenGL will multiply the normalized ... WebTo start, clip space is often conflated with NDC (normalized device coordinates) and there is a subtle difference: NDC are formed by dividing the clip space coordinates by w (also known as perspective divide).NDC boundaries are "normalized" and therefore always consistently bound.

Web21 de abr. de 2013 · Your 2D world is given in world coordinates, so you need to define a matrix that transforms world coordinates into NDCs, i.e. a projection matrix. In your shaders you then simply multiply your vertices with this projection matrix, and you get NDCs. glm::ortho / glOrtho computes such a projection matrix. WebThe goal is convert from Screen Space to NDC Space. So let's first define what those spaces are, and then we can create a conversion. Normalized Device Coordinates. NDC space is simply the result of performing perspective division on our vertices in clip space. clip.xyz /= clip.w Where clip is the coordinate in clip space.
