Functions and methods

load_geometry_matrixUse MAC1..3, not the saturated 16-bit IR registers: the existing renderer's Q12 camera coordinates regularly exceed +/-8 world units.Function template load_projection_matrixLoads projection matrix as part of Geometry Transformation Engine math and register operations.Function template load_projection_screenH is the pixel focal length shared by both axes; offsets are the screen centre.Function project_geometry_vertexCamera output is Q8 with Y up.Function transform_geometry_vertexPerforms `transform geometry vertex` as part of Geometry Transformation Engine math and register operations.Function

Fields, variables and values

gte_projection_flagsPerspective path.Variable gte_shared_origin_limitLargest Q8 chunk origin that keeps origin + any int16 Q12 vertex within the GTE's 16-bit vector inputs.Variable
