The ball is one of the most commonly used elements in ray tracing, and is also used in bounding box algorithms due to the easiest calculation intersection. therefore, an in-depth study of this section of the problem solution. first, a simple algebraic solution is derived. then the special condition of the problem is investigated, and a more effective geometrical solution is proposed. The comparison of the a
of writing is similar to "Advanced Global Illumination" (AGI), but AGI is mainly about path tracking and radiation theory two methods to tell, others such as photon mapping has some introduction, but the space is very short This book will not only introduce the path tracking and radiation theory, such as offline global lighting technology, will also introduce the more popular distance field, Voxel and other real-time global lighting technology, and this book combined with Unreal engine and othe
this August, a large number of game developers walked into Unite 2014 and gathered at the Seattle Center to attend the Unite eighth annual meeting. In a series of exciting meetings and keynote speeches, Jens Fursund, from our PowerVR Ray tracing team, introduced the upcoming Unity 5 Light mapping editor, which uses ray-tr
Light tracing is one of the mainstream rendering technologies currently. It can easily simulate complex lighting effects and generate high-quality images, which has been widely used in many fields, such as realistic rendering, virtual reality, visualization, and computer animation. However, the computing overhead of the ray tracing algorithm is large, which hinde
Camera, the laser harness will narrow, and the object will become larger on the screen (see figure 2 ). If you rotate this plane (camera point
), You will see different perspectives. This is very interesting. Different viewing angles and career things,
Is only a by-product of logic.
Scenario
Next, we need a scenario for ray tracing. The scenario consists of objects (primitive): geometric objec
Ray tracing is one of the most famous techniques in the field of graphics, the first of which is the point of view (camera, eye) passing through the center of the pixel, emitting a ray, the main ray (secondary light refers to the light emitted from the surface of the object, such as reflection or refraction). This step

I spent a day writing my first ray tracing after lrj's guidance !!
First, we will try to add new elements, such as adding a sphere or a texture.
First, there is a mirror:
Then, the last one has a refraction
(There is also the phenomenon of total reflection !)
Er ~~~ Is it very serious? I learned a anti-sawtooth skill, but it still has a little effect:
In addition, the comparison of anti-aliasing (co
Today, I spent another day on ray tracing, but obviously, I have gained a lot.
First, it took half an hour to push the form of Sphere reflection and refraction, and then changed the position of the light source. The first figure shown below is as follows:
I was completely shocked. Why did it suddenly become so good? (We can compare the figure of yesterday)
Whack reminded me that I pulled the light source
