Constructor & Destructor Documentation

◆ BulletHeightfieldShape() [1/3]

BulletHeightfieldShape::BulletHeightfieldShape ( const PNMImage & image,
PN_stdfloat max_height,
BulletUpAxis up = Z_up )
explicit

Creates a collision shape suited for terrains from a rectangular image.

Stores the image's brightness values in a vector Bullet can use, while rotating it 90 degrees to the right.

Definition at line 27 of file bulletHeightfieldShape.cxx.

References PNMImage::get_bright(), PNMImageHeader::get_x_size(), and PNMImageHeader::get_y_size().

◆ BulletHeightfieldShape() [2/3]

BulletHeightfieldShape::BulletHeightfieldShape ( Texture * tex,
PN_stdfloat max_height,
BulletUpAxis up = Z_up )
explicit

Creates a collision shape suited for terrains from a rectangular texture.

Alternative constructor intended for use with ShaderTerrainMesh. This will do bilinear sampling at the corners of all texels. Also works with textures that are non-power-of-two and/or rectangular.
