The Local Action Center works on multiple layers at a time for fast and easy changes. Select disparate edges or polygons in your model and act on them as one, locally. LightWave Modeler allows you to impact a group of items all at once in the Local Action Center. Additionally, instances of Gimbal lock can be avoided and items you are animating can be allowed to follow a more natural rotation order. This allows for an easier transition from other applications to LightWave. LightWave 2020 provides the ability to change Rotation Order per item and is saved with the scene file. Visualize Node – Grid viewer with options.VectorGrid Split and Merge – Split and merge Vector grids for further experimentation.Partio Node – Load Houdini.HClassic particle files.Level Set Morph – Morph between level set grids.Combine Math Node – Combines grids using math operators.Analysis Node – Grid creation Gradient, Curvature, Laplacian, Closest Point, Divergence, Curl, Magnitude, Normalize.Advect Point Node – Advect particles by velocity grid.Also included in the new OpenVDB toolset is: What you gain is the power of Houdini particles with the simplicity of the LightWave interface. Leading the pack in the LightWave OpenVDB roster is support for Partio particle objects. Now, you have the option to select a simple artist-friendly shading option or complete control for the look you desire. With AFC Hair Shader (Artist Friendly Control - a simplified approach) the specular settings are divided into two sections: Primary, for reflection of the front side of the stroke and Secondary for the reflection bounced off the backside of the stroke. The five inputs: Color, Cutical Tilt, Roughness, Radial Roughness and Index of Refraction provide a simple interface for spectacular results. Principled Hair Material is based on the Principled BSDF settings. The new hair shaders in LightWave 2020 deliver more realistic hair leveraging the physical-based renderer. Using the new render engines independently or in concert will assure you get the real - world render results you seek, with higher quality and more control. LightWave, long known for the beauty of its render engine, gains new advancements in LightWave 2020 with the redesign of the Global Illumination rendering engine, bringing two versions for artists: Brute Force, an unbiased radiosity engine, and Irradiance Cache, an interpolated radiosity engine. Two New Global Illumination Render Engines With the ability to model, animate, and render stunningly realistic imagery and animation, LightWave allows you to create new worlds, build your brand and shatter expectations. Affordable, complete, easy to learn, and use, LightWave is well established as one of the leading 3D systems on the market. Finally, the performance of HARIS is verified through field tests, in which the solar radiance data with an average signal-to-noise ratio of 438.93 is obtained.NewTek LightWave 3D® is designed for the independent artist who desire control of their vision from start to finish. The calibration results show that HARIS has an average spectral resolution of 0.33 nm and a field-of-view of 3.085 × 0.03° with an average spatial sampling interval of 0.0138°. HARIS response is associated with the observed target through a calibration process, which uses a monochromator with a supercontinuum laser for the spectral calibration, an integrating sphere with a spectrophotometer for the radiometric calibration and a meridian for the geometric calibration is employed to correct for distortions.

HARIS is a transmissive imaging spectrometer that uses a compact transmissive optical system combined with reflective grating spectroscopy, while an area scan CMOS detector is used as the photosensitive element for the observations. High-resolution oxygen A-band radiance imaging spectrometer (HARIS) is an imaging spectrometer that operates in the oxygen A-band, which is designed for the observation of the direct solar radiance that passes through the atmosphere. The signal in this band has wide dynamic range and can be used to invert several atmospheric parameters, such as air pressure and atmospheric optical depth, at different altitudes. The oxygen A-band (759–770 nm) is a commonly used band for atmospheric observations.
