ofConePrimitive

class methods

Extends

This class extends others, you can call their methods on an instance of ofConePrimitive too:

The ofConePrimitive allows you to create a 3D cone. Like all primitives it allows you to set the size, draw it, set positions, etc, as a simple example:


void setup()
{

    cone.set( coneRadius, coneHeight, coneRadiusSegments, coneHeightSegments );
}

void draw()
{

    cone.setPosition(ofGetWidth()*.2, ofGetHeight()*.75, 0);
    cone.rotate(spinX, 1.0, 0.0, 0.0);
    cone.rotate(spinY, 0, 1.0, 0.0);

    // get all the faces from the cpme, handy when you want to copy
    // individual vertices or tweak them a little ;)
    vector<ofMeshFace> triangles = cone.getMesh().getUniqueFaces();

    // now draw
    cone.draw();
}

To draw a texture over any primitive, simply bind the ofTexture instance and then draw your primitive:


texture.getTextureReference().bind();
// now draw
cone.draw();

Beware of the cone texture coordinates, they're a little strange.

ofConePrimitive()

ofConePrimitive::ofConePrimitive()

ofConePrimitive(...)

ofConePrimitive::ofConePrimitive(float radius, float height, int radiusSegments, int heightSegments, int capSegments=2, ofPrimitiveMode mode=OF_PRIMITIVE_TRIANGLE_STRIP)

~ofConePrimitive()

ofConePrimitive::~ofConePrimitive()

getCapIndices()

int ofConePrimitive::getCapIndices()

This returns a vector of the indices of vertices that make up the cap (as opposed to the cone indices)

getCapMesh()

ofMesh ofConePrimitive::getCapMesh()

This returns an ofMesh made up of the cap (as opposed to the cone)

getConeIndices()

int ofConePrimitive::getConeIndices()

This returns a vector of the indices of vertices that make up the cone (as opposed to the cap indices)

getConeMesh()

ofMesh ofConePrimitive::getConeMesh()

This returns an ofMesh made up of the cone (as opposed to the cap)

getHeight()

float ofConePrimitive::getHeight()

This returns the height of the cone.

getRadius()

float ofConePrimitive::getRadius()

This returns the radius of the cap

getResolution()

glm::vec3 ofConePrimitive::getResolution()

This returns the resolution of the cone (rather than the cap)

getResolutionCap()

int ofConePrimitive::getResolutionCap()

This returns the resolution of the cap (rather than the cone)
