this is a 3d renderer i made in a few hours based of the Perspective Correct Texture Mapping equations and it is very laggy, only getting ~100,000 texture calculations per second (performance is destroyed based off of where the camera looks and amount of polygons existing not just onscreen). the thing uses a really bad way of changing camera angle because it uses mouse position and you can move with the arrows and wasd with vertical controlled by space and shift you can use the project itself by putting in the vertex xyz,uv and for every third vertex (you need vertexes in multiples of 3) you put in a value for texture offset so you can have multiple textures in the texture list. this project will not be updated because it is not so significant to me
myself working on it in just a few hours (i turned the equations in to set variable to) Paul Heckbert (created the texture mapping form and its equations) random guy who posted an image on google i cannot remember for texture (sorry you have been forgotten) random website on google i cannot remember for my ability to access the equations. my computer for not blowing up in my face running this. again myself for not getting bored and doing something else because I got bored a little again
