Member Function Documentation
◆ bounding_box()
| const Rect& fastuidraw::FilledPath::bounding_box | ( | void | ) | const |
Returns the the bounding box of the FilledPath.
◆ number_subsets()
| unsigned int fastuidraw::FilledPath::number_subsets | ( | void | ) | const |
Returns the number of Subset objects of the FilledPath.
◆ root_subset()
| Subset fastuidraw::FilledPath::root_subset | ( | void | ) | const |
Returns the root Subset, i.e. the Subset that encompasses the entire FilledPath.
◆ select_subsets()
| unsigned int fastuidraw::FilledPath::select_subsets | ( | ScratchSpace & | scratch_space, |
| c_array< const vec3 > | clip_equations, | ||
| const float3x3 & | clip_matrix_local, | ||
| unsigned int | max_attribute_cnt, | ||
| unsigned int | max_index_cnt, | ||
| c_array< unsigned int > | dst | ||
| ) | const |
Fetch those Subset objects that have triangles that intersect a region specified by clip equations.
- Parameters
-
scratch_space scratch space for computations. clip_equations array of clip equations clip_matrix_local 3x3 transformation from local (x, y, 1) coordinates to clip coordinates. max_attribute_cnt only allow those Subset objects for which Subset::painter_data() have no more than max_attribute_cnt attributes. max_index_cnt only allow those Subset objects for which Subset::painter_data() have no more than max_index_cnt attributes. [out] dst location to which to write the Subset ID values
- Returns
- the number of Subset object ID's written to dst, that number is guaranteed to be no more than number_subsets().
◆ select_subsets_no_culling()
| unsigned int fastuidraw::FilledPath::select_subsets_no_culling | ( | unsigned int | max_attribute_cnt, |
| unsigned int | max_index_cnt, | ||
| c_array< unsigned int > | dst | ||
| ) | const |
In contrast to select_subsets() which performs hierarchical culling against a set of clip equations, this routine performs no culling and returns the subsets needed to draw all of the FilledPath.
- Parameters
-
max_attribute_cnt only allow those chunks for which have no more than max_attribute_cnt attributes max_index_cnt only allow those chunks for which have no more than max_index_cnt indices [out] dst location to which to write the Subset ID values
- Returns
- the number of Subset object ID's written to dst, that number is guaranteed to be no more than number_subsets().
◆ subset()
| Subset fastuidraw::FilledPath::subset | ( | unsigned int | I | ) | const |
Return the named Subset object of the FilledPath.
