How to pass particle position to Vertex Buffer?
I have particle and particle system class. In my main program, I created an instance of particle system and initialized the particles in it. In the display function, I would like to pass the position of all particles to the Vertex buffer in one shot. But I’m not sure of the notation used to access all position vertices from the.
How to access all vertex vertices from the?
But I’m not sure of the notation used to access all position vertices from the. I tried something like this:
How to get multiple objects in array to point in same direction?
The five planes in the x axis are the grouped aircraft. The circle array and the plane array (vertical) are not pointed in the same direction. I’d like to be able to specify the z axis rotation of each individual of the group. I was able to get them to point in the same direction on the plane array, but that is not the objective. Any ideas?
Can a circle array contain more than one object?
The circle array and the plane array (vertical) are not pointed in the same direction. I’d like to be able to specify the z axis rotation of each individual of the group. I was able to get them to point in the same direction on the plane array, but that is not the objective. Any ideas? Any single array can only contain instances of one object.
How is the vertex position of a sphere calculated?
The normalized vector from the center of each sphere to the vertex is used to look up the reflecting triangle in the associated explosion map. Although neither triangle may be correct, the reflected vertex can be positioned with reasonable accuracy by combining the results of both explosion maps to produce an approximation.
What do you do with the normalized vector at the vertex?
The normalized vector pointing from the sphere center to the vertex is mapped into the explosion map to find a triangle ID. The mapped point formed from the vertex and the mapped triangle vertices are used to compute barycentric coordinates.
