TriRasterInfo< T, TT > Class Template Reference

#include <TFRasterize.h>

List of all members.

Detailed Description

template<class T, class TT = Triangle<T>>
class TriRasterInfo< T, TT >

TriRasterInfo: a class to help you setup rasterization.

Works kind of like an iterator, here is an example: 

     TriRasterInfo ri(imageSizeX, imageSizeY);
     for(...)/// for each triangle
     {  
        ri.setTri(someTriangle);
        while(!ri.end())
        {
            /// position of fragment is ri.x() and ri.y()
            /// you can interpolate values using the interp*() functions
            ++ri;  /// increment to the next pixel
        }
     }

any structure that returns a point using "[]" will work as the triangle type, you could just use an array of vec3<>'s. TODO: make this work for c arrays of c arrays??

since gutz::intersect2D() is more general than we need for this algorithm, I optimized it by removing terms that will always be zero. And assume that we don't need to check for divide by zero r1: p = (0,yp), d=(1,0) [d1x, d1y] dot Perp([d2x,d2y]) const T div = -r.d::y; /// removed check for x/0 if(!div) return std::numeric_limits<T>::infinity();

There is one additional check made to insure that the start and end edges are not horizontal, if they are we swap immediately. If two are horizontal, we don't have any pixels to be rendered. Users need not worry about this, it's just an explanation of how this function sets things up.

set internal triangle

alias Tri* to a Tri, for easier access

which of the triangle points is smallest in Y (by index)

Init bounding box ( and starting point for loose ) (by integer value)

need to capture this to see if we have any usefull pixels

starting Y position, first scan line

which case are we in for "tight" rendering

case 1

start edge is horizontal

end edge is horizontal

case 2

precompute barycentric constants

initialize them

report if there are any pixels that need to be rendered

build rays for tight rendering. rays always point in +y direction these correspond to case 1 above

init the tmp ray, only the .p::y value will be modified... should ride the x=0 axis, point toward (1,0,0) tmpr = Ray3(Vec3(T(0.0),r[se].p::y + r[se].d::y/T(2.0),T(0.0)), Vec3(T(1.0), T(0.0), T(0.0)));

now that we have edge orders figured out... set the current x position
