Virtual Shadow Depth Cube Texture (VSDCT) without indirection texture

WebThe Streaming Virtual Texturing system (SVT) divides textures into tiles. At runtime, when SVT samples a texture, it does the following: It samples an indirection texture, calculates the non-virtual UVs, and samples a cache texture with these UVs. It translates the virtual UVs to a tile ID, and binds an additional render target that receives ... Web4 mrt. 2015 · A texture indirection can be considered a node in the texture dependency chain. Each node contains a set of texture instructions which execute in parallel, followed by a sequence of ALU instructions. A dependent texture instruction is one that uses a temporary as an input coordinate rather than an attribute or a parameter. boarlin minecraft

Web11 aug. 2008 · Page address is translated per-fragment using an indirection texture that maps a page in virtual address to a region in the physical texture cache [11]. Van Waveren [17] ... The Page Indirection texture is a texture with one pixel for each page/tile in the virtual texture, that will map the incoming UVs to the Page Table cache texture that has the actual texel data. This texture can get quite large, so it must use some compact format, like RGBA 8:8:8:8 or RGB 5:6:5. Meer weergeven The main reason for Virtual Texturing (VT), or Sparse Virtual Textures, as it is sometimes called, is as a memory optimization. … Meer weergeven Zooming in/out and abrupt camera movement are the hardest things to handle in a VT setup.
