I am doing ray tracing and I have to make intersection between the ray and polynomial so I got the following equation and I have to solve it for t.
A(21).*(Y.^5) + (A(20).*(Y.^4)).*X + A(19).*(Y.^4) + (A(18).*(Y.^3)).*(X.^2) + (A(17).*(Y.^3)).*X + A(16).*(Y.^3) + (A(15).*(Y.^2)).*(X.^3) + (A(14).*(Y.^2)).*(X.^2) + (A(13).*(Y.^2)).*X + A(12).*(Y.^2) + (A(11).*(Y)).*(X.^4) + (A(10).*Y).*(X.^3) + (A(9).*Y).*(X.^2) + (A(8).*Y).*(X) + (A(7).*Y) + A(6).*(X.^5) + A(5).*(X.^4) + A(4).*(X.^3) + A(3).*(X.^2) + A(2).*X + A(1) - Z = 0;*
While:
X = (px +t*dx); Y = (py +t*dy); Z = (pz +t*dz);
so I want to get t in respect to the other variables. ( I have all the other variables but I don't know how to calculate it )
Please support Many thanks in advance
