In other posts, you mentioned the reason why my program will get stuck. What should I do to avoid it. Thank you very much

Drleviathan, thank you very much for your help. I want to realize the movement of the ball in the imported model (similar to a tube). I want to place the ball in a certain position inside the model, and then fall under the influence of gravity and collide with the inner wall of the model. However, a...

I imported a 3D model of. Obj. I want to place small balls in some positions of the model, but I can't find a certain internal position of the 3D model, as shown in the figure. What should I do? Thank you for your time http://m.qpic.cn/psc?/76b33374-4a0f-4a5d-99b2-b6eef432e262/M4X34P*UDwP*fok89st23w...

I have encountered this problem, can you tell me what I should do? thank you Error 2 error C2653: 'CProfileManager' : is not a class or namespace name

I want to achieve the collision effect of small balls, but I found that when I increase the number of small balls, the program becomes stuck. What should I do to solve this problem? Thank you very much

I created a cuboid rigid body, how should I get all the coordinates of its interior space. Thank you very much.

I really appreciate your help. but how can I increase the thickness of the rigid body?

I set up a cuboid, and set up a small ball in the inside of the cuboid to fall under the influence of gravity and spring up elastically. I set the Euler angle of the cuboid rotation, but I found that when the Euler angle changes a little, the ball can move normally, but when I increase the degree, t...

So the code might look like this:

Code: Select all

btTransform t = body->getWorldTransform();
t.setRotation(btQuaternion(roll, pitch, yaw));
body->setWorldTransform(t);

Thank you very much

Thank you very much for your reply. I found that initobjectground() in my code was initialized only once, so btquaternion quaternion = btquaternion (yaw, pich, roll); it was also called only once, resulting in unable to change the Euler angle of the model. Can I ask if there is any way to control th...

I want to change the Euler angle in real time through the keyboard and display it through OpenGL,I put the initialization of the model in InitObjectground();But the model doesn't move when I press the key to change yaw roll glPushMatrix(); glTranslated(float(trans.getOrigin().getX()), float(trans.ge...

I set up a rigid body, and I hope that I can change his rotation by changing his Euler angle through the keyboard, and display him through OpenGL. What should I do? btQuaternion quaternion = btQuaternion(yaw, pich, roll); groundTransform.setRotation(quaternion); glRotatef(trans.getRotation().getW(),...

I want to rotate the rigid body by setting the Euler angle, but there is an error. Can you help me to see how to write it?

The btBvhTriangleMeshShape is effectively a triangle-soup with BVH tree around it. It can collide as concave mesh. The triangle faces collide on both sides so you can make dynamic things bounce around on the inner surface... as long as they aren't too small and moving too fast and/or you have conti...

Thank you very much for your help. I used the btCompoundShape and successfully implemented it. Thank you again for your help
