What is caustics in VRAY?
Caustics are everywhere — so let’s define them But, for the people in computer graphics: A caustic is any lighting contribution that goes from light source to specular (reflective or refractive), to diffuse surface, to eye (or camera).
How do you make VRAY water material?
Clean water is a very simple material. Start with an almost black diffuse color [1;1;1]. Add some Fresnel Reflections (IOR 1.33) and Refraction (make sure to enable ‘affect shadows,’ if not using caustics). The result is a basic water material.
What is caustics in lighting?
The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light. Therefore, in the photo to the right, caustics can be seen as patches of light or their bright edges. These shapes often have cusp singularities.
What are water caustics?
Caustics are patterns of light that occur when light is refracted and reflected from a surface, in our case an air/water interface. Due to the reflection and refraction occurring on water waves, water acts as a dynamic magnifying glass which creates those light patterns.
What are caustics in toxicology?
Caustics and corrosives cause tissue injury by a chemical reaction. The vast majority of caustic chemicals are acidic or alkaline substances that damage tissue by accepting a proton (alkaline substance) or donating a proton (acidic substance) in an aqueous solution.

What is caustics in 3D?
Caustics is a term that is not just utilized in the world of 3D graphics. It’s the term used that describes the patterns of light and color that occur when light rays are reflected or refracted from a surface. Caustics are a form of indirect illumination but very specific in how it happens and where it occurs.
Can you make a Vray pool with caustics?
One of the most exclusive and impressive features offered by VRay is the use of Caustics. By using this function you can create physically accurate water bodies on the cheap. Here’s a whole step-by-step method for making amazing swimming pools that just stand out and sell the project!
How are reflective caustics formed in Vray render?
Just like Refractive Caustics are formed under water, Reflective Caustics are formed in the same way via reflection. Generally such caustic effects are native to unbiased render engines, but VRay gives you full control over its use.
Can you make a photo realistic swimming pool with Vray?
Here’s an awesome method for creating PHOTO-Realistic swimming pool water with vray caustics effect. One of the most exclusive and impressive features offered by VRay is the use of Caustics. By using this function you can create physically accurate water bodies on the cheap.
What are the light patterns in a Vray pool?
VRay Caustics | Swim Pool Render. As an introduction to caustics, let me first explain what caustics really are. In layman terms, caustics are the wavy light patterns formed under clear water when sunlight refracts through any uneven water surface. You also might’ve seen similar light patterns on any ceiling near a pool.
