- /// An hkpConvexTranslateShape contains an hkpShape and an additional translation for that shape.
- /// This is useful, for instance, if you
- /// want to position child shapes correctly when constructing a compound shape.
- /// The advantage of using hkpConvexTranslateShape over hkpTransformShape is that
- /// it does not require additional agents to be created, as the hkpConvexTranslateShape is
- /// a convex shape and directly works with GSK.
- /// However, if you use the hkpConvexTranslateShape wrapping an hkpBoxShape, no hkpBoxBoxAgent will be
- /// created, but the hkpGskfAgent.
- ///
- /// On PLAYSTATION(R)3 this shape's collision detection will only be allowed to move onto an SPU if
- /// a) all its children are supported on SPU
- /// b) its total size including all its children will fit into one of the SPU's shape buffers
- /// If this is the case a call to getChildShape() on the SPU will dma in the child shape from
- /// main memory (and thus cause a code execution stall). To improve this we have added
- /// support for the situation where the child shape follows this hkpConvexTranslateShape consecutively in memory.
- /// In such a case both the hkpConvexTranslateShape and its child shape are brought in in one
- /// single dma operation. Note that this properly takes care of cascades as well, i.e. several
- /// hkConvexTranslateShapes in a row are all brought in in one go.
- /// hkpConvexTransformShape supports the same mechanism and thus works as part of such a cascade as well.
