Detecting Billboards

9 posts in this topic

When the player shoot, I draw a bullet impact billboard, sometimes the player shoot at the same target multiple times, I don't want to place multiple billboards over each others.

 

How do I detect if a billboard already exists, so I only draw it if no billboards exists on the hit point?

 

D3DXVECTOR3 triangleP0, triangleP1, triangleP2; // Intersected triangle
D3DXVECTOR3 pHitPoint; // The hit point

// --> I want to use if () statement to check if a billboard already exists here...

// Code to draw billboard here...

You would need to keep track of the hit spots on each object

@ankhd: The player could shoot at: 2.0f, 1.8f, 1.0f

 

Then shoot at: 2.0f, 1.4f, 1.0f

 

Notice, it's not the same hit spot but I shouldn't be drawing the billboard since it will still appear over another one.

 

See the sceenshot, two billboards appears over each others, I want to AVOID that:

You could calculate the distance between position of "billboard" that you want to place against position of each existing "billboards" and if it is smaller then some value  do not add it to the world. Hint: D3DXVec3LengthSq

In some games, I notice they place bullet impact billboards over each others, though they still look realistic.

 

In my case, If I draw multiple billboard over each others, they don't look realistic.

 

Do I only have to change the texture to another one that can appear realistic when placed over each others? Maybe there are some techniques like resizing existing billboard before drawing another one over it?
