Model 3 is more powerful and flexible than 2 but is less compatible.Vertex:no instruction limit.fragment:1024 instruction Limit (texture + arithmetic), temporary registers and 4 texture indirections.It is the possible to override these limits using #pragma profileoption directive.For example, #pragma pr

Yesterday when shopping to see the peace bird inside put a metal Mickey Mouse, so the occupational disease committed, has been thinking about the color of metal is what, this reflection how to write, think not come out ...Today just see the dynamic Reflection Cubic chart System This section, after reading feel very awkward, because the book is introduced in advance casing generate cubemap way instead of real-time. Then to the official documents to find real-time reflection of the code, did a mor
