From bf6529db320bc7ab3fe292e3b7288c8f71636f6e Mon Sep 17 00:00:00 2001 From: Robert Adams Date: Wed, 25 Jul 2012 10:35:34 -0700 Subject: BulletSim: Redo parameter specification so only one place has to change to have a parameter show up in the ini file and command line. Will make it much easier for the next person. --- OpenSim/Region/Physics/BulletSPlugin/BSScene.cs | 626 ++++++++++++++---------- 1 file changed, 378 insertions(+), 248 deletions(-) (limited to 'OpenSim/Region/Physics/BulletSPlugin/BSScene.cs') diff --git a/OpenSim/Region/Physics/BulletSPlugin/BSScene.cs b/OpenSim/Region/Physics/BulletSPlugin/BSScene.cs index 7cc3fe3..07a377b 100644 --- a/OpenSim/Region/Physics/BulletSPlugin/BSScene.cs +++ b/OpenSim/Region/Physics/BulletSPlugin/BSScene.cs @@ -103,6 +103,17 @@ public class BSScene : PhysicsScene, IPhysicsParameters get { return m_sculptLOD; } } + private BulletSim m_worldSim; + public BulletSim World + { + get { return m_worldSim; } + } + private BSConstraintCollection m_constraintCollection; + public BSConstraintCollection Constraints + { + get { return m_constraintCollection; } + } + private int m_maxSubSteps; private float m_fixedTimeStep; private long m_simulationStep = 0; @@ -229,6 +240,11 @@ public class BSScene : PhysicsScene, IPhysicsParameters m_maxCollisionsPerFrame, m_collisionArrayPinnedHandle.AddrOfPinnedObject(), m_maxUpdatesPerFrame, m_updateArrayPinnedHandle.AddrOfPinnedObject()); + // Initialization to support the transition to a new API which puts most of the logic + // into the C# code so it is easier to modify and add to. + m_worldSim = new BulletSim(m_worldID, BulletSimAPI.GetSimHandle2(m_worldID)); + m_constraintCollection = new BSConstraintCollection(World); + m_initialized = true; } @@ -237,116 +253,17 @@ public class BSScene : PhysicsScene, IPhysicsParameters private void GetInitialParameterValues(IConfigSource config) { ConfigurationParameters parms = new ConfigurationParameters(); + m_params[0] = parms; - _meshSculptedPrim = true; // mesh sculpted prims - _forceSimplePrimMeshing = false; // use complex meshing if called for - - m_meshLOD = 8f; - m_sculptLOD = 32f; - - shouldDebugLog = false; - m_detailedStatsStep = 0; // disabled - - m_maxSubSteps = 10; - m_fixedTimeStep = 1f / 60f; - m_maxCollisionsPerFrame = 2048; - m_maxUpdatesPerFrame = 2048; - m_maximumObjectMass = 10000.01f; - - PID_D = 2200f; - PID_P = 900f; - - parms.defaultFriction = 0.5f; - parms.defaultDensity = 10.000006836f; // Aluminum g/cm3 - parms.defaultRestitution = 0f; - parms.collisionMargin = 0.0f; - parms.gravity = -9.80665f; - - parms.linearDamping = 0.0f; - parms.angularDamping = 0.0f; - parms.deactivationTime = 0.2f; - parms.linearSleepingThreshold = 0.8f; - parms.angularSleepingThreshold = 1.0f; - parms.ccdMotionThreshold = 0.0f; // set to zero to disable - parms.ccdSweptSphereRadius = 0.0f; - parms.contactProcessingThreshold = 0.1f; - - parms.terrainFriction = 0.5f; - parms.terrainHitFraction = 0.8f; - parms.terrainRestitution = 0f; - parms.avatarFriction = 0.5f; - parms.avatarRestitution = 0.0f; - parms.avatarDensity = 60f; - parms.avatarCapsuleRadius = 0.37f; - parms.avatarCapsuleHeight = 1.5f; // 2.140599f - parms.avatarContactProcessingThreshold = 0.1f; - - parms.maxPersistantManifoldPoolSize = 0f; - parms.shouldDisableContactPoolDynamicAllocation = ConfigurationParameters.numericTrue; - parms.shouldForceUpdateAllAabbs = ConfigurationParameters.numericFalse; - parms.shouldRandomizeSolverOrder = ConfigurationParameters.numericFalse; - parms.shouldSplitSimulationIslands = ConfigurationParameters.numericFalse; - parms.shouldEnableFrictionCaching = ConfigurationParameters.numericFalse; - parms.numberOfSolverIterations = 0f; // means use default + SetParameterDefaultValues(); if (config != null) { // If there are specifications in the ini file, use those values - // WHEN ADDING OR UPDATING THIS SECTION, BE SURE TO UPDATE OpenSimDefaults.ini - // ALSO REMEMBER TO UPDATE THE RUNTIME SETTING OF THE PARAMETERS.
