Rendering Techniques Assignment 3

Ray Tracing Cylinders Assigned: Tuesday, March 18, 2003 Due: Monday, March 31, 2003 Overview For this assignment, you will add cylinder primitives to your ray tracer. Using an object-oriented approach, most of your program will apply to primitives without distinguishing between spheres and cylinders. Only a small portion of the program will ...

To handle this finite length cylinder, solve Equation 41 above. This gives, at most, two values of t.Call these t 1 and t 2.Calculate z 1 and z 2 using Equation 24 ( z 1 = z E + t 1 z D and z 2 = z E + t 2 z D) and then check and .Whichever intersection point passes this test and, if both pass the test, has the smallest non-negative value of t, is the closest intersection point of the ray with ...

Sampling In the simplest case, choose our sample points at pixel centers For better results, can supersample – e.g., at corners and at center Even better techniques do adaptive sampling: increase sample density in areas of rapid change (in geometry or lighting) With stochastic sampling, samples are taken probabilistically; converges faster than regularly spaced sampling

Intersection of line and cylinder - Ray tracing

r1v = [x1, y1, z1]; elseif z2 > zs. r1v = [x2, y2, z2]; else. Below is the code I have for the line- cylinder intersection so far. I only intend to modify a,b and c, and then put them into the code above. However, my GUI-figure doesn't display anything close to the "sphere-code". %These 3 lines is where I think the problem is (a,b,c).

1 Answer1. Show activity on this post. I assume that you are able to find the intersection points between the ray and the cylinder surface, obtained as t values along the ray. Do a similar computation to find the intersections with the planes of the two basis. You will get two pairs [tc0, tc1], [tp0, tp1].
