maxwell shaders
MAXWELL DIFFUSE SHADER Color of diffuse reflection SSS Sub-Surface Scattering Amount of light to be absorbed through the object surface Not Available Amount of light to be scattered back from sub-surface Color Map Bump Map Coef. [-999.0,+999.0] Reflection Map Range [0.0-1.0] Clip Map Clipmap Threshold Maxwell Diffuse Parameters Maps Color Defines the color of diffuse reflection. Diffuse surfaces scatter light in every direction and gives the object its color.
MAXWELL DIFFUSE SHADER EFFICIENT RENDERS AND SILK SMOOTH MATERIALS Since diffuse shader has no specular reflections, it's possible to have them rendered very quickly. When setting up your scene it would be better to consider which materials can be simulated with diffuse shader first. For example, the rendering would be painless if you use diffuse shader to achieve materials for non-specular surfaces like walls, bricks, concrete, carpets, fabrics etc.
MAXWELL PLASTIC SHADER Color of specular reflection Color of diffuse reflection Surface Roughness SSS Sub-Surface Scattering Amount of light to be absorbed through the object surface Not Available Amount of light to be scattered back from sub-surface Color Map Specular Map Bump Map Coef. [-999.0,+999.0] Glossy Map Percentage Reflection Map Range [0.0-1.0] Maxwell Plastic Parameters Color Defines the color of diffuse reflection.
MAXWELL PLASTIC SHADER ADVANCED MATERIALS WITH SPECULARITY AND GLOSSINESS Plastic shader has more parameters to achieve a wide range of real life materials. It has u and v controllable roughness, specular reflections and glossiness as a plus. Since no surface is perfect, roughness helps a lot to aviod CG look. With mapped specular, glossiness and reflectivity, it's easy to simulate complex surfaces like lacquered floors, shiny paints, plastic substances, leather, wood etc.
MAXWELL DIELECTRIC SHADER Presets Materials Amount of light energy terminated by object Controls Disperison Surface Roughness Index of Refraction Not Available Bump Map Coef. [-999.0,+999.0] Not Available Maxwell Dielectric Material Maps Type Nd and Abbe presets for different materials. Color Map Not Available Color Defines the color of dielectric material. Bump Map Applies given bitmap as a height map for the bump effect.
MAXWELL DIELECTRIC SHADER BEAUTY OF DISPERSION AND CAUSTICS Dielectrics shader has benefits of refractive materials. Refractive materials are far more time consuming due to heavy calculations like dispersion and caustics. These materials scatter some amount of light back and let some amount of the light through and emit some amount of the gathered light.
MAXWELL METAL SHADER Metal Presets Surface Roughness Bump Map Not Available Gloss Map Coef. [-999.0,+999.0] Reflection Map Percentage Range [0.0-1.0] Maxwell Metal Parameters Maps Type Measured presets for metal surfaces (Aluminium, Cobalt, Copper, Gold, Silver) which also simulates the metal's color. Color Map Not Available u and v Roughness Disperses the scattered light energy randomly to achieve a more rough surface for both (u,v) mapping directions.
MAXWELL METAL SHADER SHINY, DULL AND BRUSHED METAL SURFACES You can easily set surface roughness to achieve dull/brushed metals or change their reflectivity and glossiness with the respective controls. For more complex surfaces like partly rusty metals, plastic shader is suggested with color, specular, gloss and reflection maps. INTERACTIVE CONTENT Click here and drag mouse to test effects of roughness on metals. BUILT-IN METAL PRESETS Metal shader works with presets of measured metal surfaces.
MAXWELL EMITTER Warmth presets Power of emission in terms of corresponding units Intensity calculation method: Unit setup alters the calculation of the emitted energy given by intensity. Color of custom illuminant Not Available Maxwell Emitter Parameters Illuminants You can choose spectral data presets for some standard illuminants like A, B, C, D65, D75, COOL_WHITE. Light Color Intensity Power of emission in terms of corresponding units.
maxwell camera
MAXWELL CAMERA FOV Field of View Lens Opening th [1/n of lens surface] Speed of Shutter [n times for 1 sec] Shape of Diaphram Focal Distance Blade amount Camera Target Maxwell Camera Blade rotation Type of Lens Maxwell Camera Parameters fStop Simply, fStop defines lens opening. Diaphram is closing lens opening as the iris of an organic eye. The default value 8 means the 1/8th of area of lens surface is open and able to let the light in. Shutter speed Shutter works like a curtain.
MAXWELL CAMERA PLAY WITH fStop Test how fStop affects the view at a constant Shutter Speed and lens diameter. In this example the parameters are: Lens Target Shutter fStop 50 mm 45 mm 1/30 [2.0 - 8.0] INTERACTIVE CONTENT Click here and drag mouse horizontally to spin fStop value. PLAY WITH Shutter Speed Test how Shutter Speed affects the view at a constant fStop and lens diameter. In this example the parameters are: Lens Target Shutter fStop 50 mm 45 mm [1/30 - 1/2] 8.
maxwell environment & rendering system
IMPORTANT THINGS TO KNOW BEFORE YOU START RENDERING * Always use Maxwell Shaders for materializing your objects. Any other shader won't be accepted by the shader. * Always use a Maxwell Camera, do not use the camera which comes with your 3D application. * Keep the geomerty of emitter objects as simple as possible. Most of the time, simple planes would be enough to setup a scene. * Make sure the sum of diffuse and specular reflectances of your plastic materials DO NOT exceed 1.
