| static BOOL CC3BarycentricWeightsAreInsideTriangle | ( | CC3BarycentricWeights | bcw ) | [inline, static] |
Returns whether the specified barycentric weights indicate a location inside a triangle.
To be inside a triangle, none of the weights may be negative. If any of the weights are negative, the specified barycentric weights represent a location outside a triangle.

Returns a bounding box that has the same dimensions as the specified bounding box, but with each corner expanded outward by the specified amount of padding.
The padding value is added to the maximum vector, and subtracted from the minimum vector.
| static CC3BoundingBox CC3BoundingBoxAddUniformPadding | ( | CC3BoundingBox | bb, |
| GLfloat | padding | ||
| ) | [inline, static] |
Returns a bounding box that has the same dimensions as the specified bounding box, but with each corner expanded outward by the specified amount of padding.

Returns the geometric center of the specified bounding box.
| static BOOL CC3BoundingBoxContainsLocation | ( | CC3BoundingBox | bb, |

Returns the smallest CC3BoundingBox that contains both the specified bounding box and location.
If the specified bounding box is null, returns a bounding box of zero size at the specified location.
| static BOOL CC3BoundingBoxesAreEqual | ( | CC3BoundingBox | bb1, |
| CC3BoundingBox | bb2 | ||
| ) | [inline, static] |
Returns whether the two bounding boxes are equal by comparing their respective components.
| static CC3BoundingBox CC3BoundingBoxFromMinMax | ( | CC3Vector | minVtx, |
| CC3Vector | maxVtx | ||
| ) | [inline, static] |
Returns a CC3BoundingBox structure constructed from the min and max vertices.
| static BOOL CC3BoundingBoxIsNull | ( | CC3BoundingBox | bb ) | [inline, static] |
Returns whether the specified bounding box is equal to the null bounding box, specified by kCC3BoundingBoxNull.
| static CC3BoundingBox CC3BoundingBoxMake | ( | GLfloat | minX, |

Returns a CC3BoundingBox structure constructed from the min and max components.
| static CC3BoundingBox CC3BoundingBoxScale | ( | CC3BoundingBox | bb, |
| CC3Vector | scale | ||
| ) | [inline, static] |
Returns a bounding box constructed by scaling the specified bounding box by the specified scale value.
Scaling can be different along each axis of the box.
This has the effect of multiplying each component of each of the vectors representing the minimum and maximum corners of the box by the corresponding component in the scale vector.
| static CC3BoundingBox CC3BoundingBoxScaleUniform | ( | CC3BoundingBox | bb, |
| GLfloat | scale | ||
| ) | [inline, static] |
Returns a bounding box constructed by scaling the specified bounding box by the specified scale value.
The same scaling is applied to each axis of the box.
This has the effect of multiplying each component of each of the vectors representing the minimum and maximum corners of the box by the scale value.
| static CC3BoundingBox CC3BoundingBoxUnion | ( | CC3BoundingBox | bb1, |
| CC3BoundingBox | bb2 | ||
| ) | [inline, static] |
Returns the smallest CC3BoundingBox that contains the two specified bounding boxes.
If either bounding box is the null bounding box, simply returns the other bounding box (which may also be the null bounding box).
Returns the distance from the specified location to the specified plane.
The distance is returned in terms of the length of the normal. If the normal is of unit length, then the distance is in absolute units.
Returns whether the specified ray intersects the specified sphere.
| static BOOL CC3DoesSphereIntersectSphere | ( | CC3Sphere | sphereOne, |
| CC3Sphere | sphereTwo | ||
| ) | [inline, static] |

The returned weights are specified in the same order as the vertices of the face.
The specified location should be on the plane of the specified face.
If the location is on the plane of the specified face, the three returned weights will add up to one. If all three of the returned weights are positive, then the location is inside the triangle defined by the face, otherwise, at least one of the returned weights will be negative.
Returns the location of the center of the specified face, calculated as the mathematical average of the three vertices that define the face.
| static CC3FaceIndices CC3FaceIndicesMake | ( | GLuint | i0, |
| GLuint | i1, | ||
| GLuint | i2 | ||
| ) | [inline, static] |
