)

OBB-OBB overlap test using the separating axis theorem.

  • original code by Gomez / Gamasutra (similar to Gottschalk's one in RAPID)
  • optimized for AABB trees by computing the rotation matrix once (SOLID-fashion)
  • the fabs matrix is precomputed as well and epsilon-tweaked (RAPID-style, we found this almost mandatory)
  • Class III axes can be disabled... (SOLID & Intel fashion)
  • ...or enabled to perform some profiling
  • CPU comparisons used when appropriate
  • lazy evaluation sometimes saves some work in case of early exits (unlike SOLID)
Parameters
ea[in] extents from box A
ca[in] center from box A
eb[in] extents from box B
cb[in] center from box B
Returns
true if boxes overlap

Generic collision query for generic OPCODE models. After the call, access the results with:

Parameters

world0[in] world matrix for first object, or null
world1[in] world matrix for second object, or null
Returns
true if success
Warning
SCALE NOT SUPPORTED. The matrices must contain rotation & translation parts only.

Triangle-Box overlap test using the separating axis theorem. This is the code from Tomas Möller, a bit optimized:

  • with some more lazy evaluation (faster path on PC)
  • with a tiny bit of assembly
  • with "SAT-lite" applied if needed
  • and perhaps with some more minor modifs...
Parameters

Returns
true if triangle & box overlap

Updated June 1999: removed the divisions – a little faster now! Updated October 1999: added {} to CROSS and SUB macros

int NoDivTriTriIsect(float V0[3],float V1[3],float V2[3], float U0[3],float U1[3],float U2[3])

Parameters
V0[in] triangle 0, vertex 0
V1[in] triangle 0, vertex 1
V2[in] triangle 0, vertex 2
U0[in] triangle 1, vertex 0
U1[in] triangle 1, vertex 1
U2[in] triangle 1, vertex 2
Returns
true if triangles overlap
