Our aim is to find image pixel colors based on what the camera would be looking at that pixel. To do so, we shoot rays from the camera into the scene, get the intersection points from the scene and based on the material of the intersected object, set the pixel color. This is done over multiple iterations to get a physically correct global illumination. On every iteration, we bounce the ray multiple times based on the material to get a good approximation for a pixel. As every ray is independent of the other, this becomes an embarrassing parallel algorithm. -This is due Thursday, September 24 evening at midnight. - -**Summary:** -In this project, you'll implement a CUDA-based path tracer capable of rendering -globally-illuminated images very quickly. -Since in this class we are concerned with working in GPU programming, -performance, and the generation of actual beautiful images (and not with -mundane programming tasks like I/O), this project includes base code for -loading a scene description file, described below, and various other things -that generally make up a framework for previewing and saving images. - -The core renderer is left for you to implement.

The features implemented in the project are: + +* Ray parallel path tracing over the GPU +* Anti Aliasing +* Basic diffused surface +* Specular surfaces implemented by sampling a light source at random +* Mirror surface +* Refractive surfaces implemented with Fresnels reflectance +* Depth of field +* Direct Illumination by sampling a light source at random +* Subsurface Scattering +* Work Efficient stream compaction with shared memory to remove dead rays quickly +* Effects like color bleeding, caustics, soft shadow can be observed + +### Implementation Details + +Let us look at the method used to implement each of the features: + +##### Ray parallel path tracing over the GPU -> +As mentioned above, this is an emabarrisingly parallel algorithm as all rays are independent of each other. Hence we can send all the rays in parallel to a CUDA kernel for color calculations. + +##### Anti Aliasing -> +A pixel is not a point but a small square area. It is possible that more than one color exists in a pixel and hence the color of the pixel should be the average of all these colors. If we always sample the center of the pixel, we will get the same color and the edges in our final render would be stairstepped. This is called aliasing. To overcome this problem, I jitter the pixel sampling point to select random points within a pixel area. This gives us a better approximation of the color at that pixel and hence a better render. This is called antialiasing. You can see the comparison between the Aliased and an Antialiased image below: + + + +##### Diffused Surface -> +For a good approximation of the color at a diffused surface, we need to bounce the ray in all possible directions and average the contributions of the color values of all these rays. To get the bounce direction, we take a direction in a hemishpere in the direction of the intersection normal (code provided). This acts as the ray direction for the next iteration. + +##### Specular Surface -> +To get a specular highlight, we calculate the color based on the half angle and the specular exponent. To get the half angle, we have to get the ray going to a light. Now as the light is an area light, we sample a random point on the light source to get the light vetor. +Now to decide of the color of the this ray would be a specular or a diffused contribution, we generate a random number between 0 and 1 and take a 30-70 split between the rays. Hence 30% rays contribute specular and 70% contribute diffused. This gives us a desired result. + +##### Mirror Surface -> +To get a mirror like effect, we reflect the incoming ray from the surface with respect to the normal. + +##### Refractive Surface and Fresnels Reflectance -> +Materials like glass, water etc are refractive surfaces. To implement this, I take the incoming ray and refract it with inside the object. Next, I take this ray and refract it again to go come out. This gives us a transparency like effect. Make sure you feed the correct refractive indices to the refract function. +To make the refraction more physically correct, I implemented Fresnels reflection. As per this law, any incoming light is both refracted and reflected by some amount. The probability of each happening is based on the refractive index of the object. For the calculations I refered to PBRT Page 435. This gave me the probability split between reflection and refraction. The next step is to implement both and add their contributions based on the probability. To make a material display fresnel property, make the flag for both refraction and reflection to 1 in the scene file (explained below). + + + +##### Depth of Field -> +This is a very interesting effect that can be observed in many photographs where some part of the image is in sharp focus while the other is blurred out. To implement this effect, I used the focal length and aperture parameters of the camera. Assume that there is a sphere centered at the camera position and of the radius of the focal length. We get the intersection of all intitial rays with this sphere. Next, we keep this as the final point but jitter the ray's origin based on the aperture of the camera. The new ray direction will be from this jittered origin to the intersection point. What happens now is that all the points wihtin that focal length are in focus but all others are out of focus. To enable Depth of Field, make the DOF flag to 1 in `pathtrace.cu`. + + + +##### Direct Illumination -> +The concept of direct illumination is that if any ray is alive after the ray depth, then we can take that ray directly to the light. If it can reach the light then we add its contribution to the final image. This helps in generating better looking renders. Also, we can reduce the trace depth and get a similar result with direct illumination. +The important part of this is sampling the lights. For this I borrowed the code from CIS 560 to sample cubes and spheres. First I randomly select a light and then take a random point on that light. This gives me a good sampling of all the light sources. To enable Direct illumination, make the DI flag to 1 in `pathtrace.cu`. + + + +##### Subsurface Scattering -> +Getting physically accurate subsurface scattering effect is very expensive to compute (Algorithm explained in PBRT). I tried to hack around it got a decent effect. +In my method, I get a random reflection direction within the hemishpere from the intersection point. Then I move the ray in this direction by some distance which is the SSS value in the scene file. Now I create a new ray that goes from this point to the center of the object. I find the intersection of this ray with the same object and get the new point on the geometry. This point acts as the origin for the ray bounce. To get the direction, I choose a random ray direction in the hemisphere. +For better visual results, I took a 50-50 split between the sub surface scattering and diffused bounce. This gives me some nice results as shown below. The sphere on the left is diffused while the one on the right shows sub surface scattering properties. + + + +##### Work efficient Stream Compaction -> +In the path tracer, the rays that do not hit any object or hit a light are considered to be dead. If we hit the light then we are done and we can add the color to the corresponding pixel. If it does not hit anything then also we are done. So we mark all these rays as dead. In the next step, we have to remove all these rays from our array and consider only the one's that are alive. The work efficient stream compaction helps speeding this process by doing it in parallel over the shared memory of a block. + +##### Color Bleeding, Caustics and Soft Shadow -> +These are real life effects that we get for free with the path tracer. In the images you can see that the red and green color of the surrounding bleeds into the white back wall giving it a little color. +Caustics is observed with refractive materials. When the light goes through a refractive surface, it gets concentrated on the other side. This can be observed in the image. +Soft shadows can be observed because we have area lights. + + ### Scene File Format -This project uses a custom scene description format.
