Web19 de jul. de 2024 · One of the key differences between OpenGL and Vulkan -and something that needs careful consideration when porting to Vulkan, is the coordinate … These NDC are then given to the rasterizer to transform them to 2D coordinates/pixels on your screen. Transforming coordinates to NDC is usually accomplished in a step-by-step fashion where we transform an object's vertices to several coordinate systems before finally transforming them to NDC. Ver mais To transform the coordinates from one space to the next coordinate space we'll use several transformation matrices of which the most important are the model, view and projection matrix. Our vertex coordinates first start … Ver mais Local space is the coordinate space that is local to your object, i.e. where your object begins in.
