Render Simple TOP

Summary

The Render Simple TOP renders a single POP with a basic transform, light and an optional texture map or material. Other controls include orthographic/perspective, object color and background RGBA.

The camera is located along the Z-axis. The Normalize Geo parameter will translate and uniformly scale the POP geometry to fit in a box of size 2 in at the origin.

You can render in wireframe or substitute the material with any MAT. The POP's render/display flags are ignored.

Render Simple does not require a Camera COMP, Geometry COMP or Light COMP that is required by the more full-featured Render TOP.

Parameters - Common Page

Output Resolution outputresolution - ⊞ - quickly change the resolution of the TOP's data.

• Use Input useinput - Uses the input's resolution

• Eighth eighth - Multiply the input's resolution by that amount.

• Quarter quarter - Multiply the input's resolution by that amount.

• Half half - Multiply the input's resolution by that amount.

• 2X 2x - Multiply the input's resolution by that amount.

• 4X 4x - Multiply the input's resolution by that amount.

• 8X 8x - Multiply the input's resolution by that amount.

• Fit Resolution fit - Grow or shrink the input resolution to fit this resolution, while keeping the aspect ratio the same.

• Limit Resolution limit - Limit the input resolution to be not larger than this resolution, while keeping the aspect ratio the same.

• Custom Resolution custom - Directly control the width and height.

Resolution resolution - ⊞ - Enabled only when the Resolution parameter is set to Custom Resolution. Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.

• W resolutionw -

• H resolutionh -

Resolution Menu resmenu - A drop-down menu with some commonly used resolutions.

Use Global Res Multiplier resmult - Uses the Global Resolution Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Resolution Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this TOP is affected by the global multiplier.

Output Aspect outputaspect - ⊞ - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)

• Use Input useinput - Uses the input's aspect ratio.

• Resolution resolution - Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square.

• Custom Aspect custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.

Aspect aspect - ⊞ - Use when Output Aspect parameter is set to Custom Aspect.

• Aspect1 aspect1 -

• Aspect2 aspect2 -

Aspect Menu armenu - A drop-down menu with some commonly used aspect ratios.

Input Smoothness inputfiltertype - ⊞ - This controls pixel filtering on the input image of the TOP.

• Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.

• Interpolate Pixels linear - Uses linear filtering between pixels. This is how you get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.

• Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.

Fill Viewer fillmode - ⊞ - Determine how the TOP image is displayed in the viewer.

NOTE:To get an understanding of how TOPs work with images, you will want to set this to Native Resolution as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.

• Use Input useinput - Uses the same Fill Viewer settings as it's input.

• Fill fill - Stretches the image to fit the edges of the viewer.

• Fit Horizontal width - Stretches image to fit viewer horizontally.

• Fit Vertical height - Stretches image to fit viewer vertically.

• Fit Best best - Stretches or squashes image so no part of image is cropped.

• Fit Outside outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer.

• Native Resolution nativeres - Displays the native resolution of the image in the viewer.

Viewer Smoothness filtertype - ⊞ - This controls pixel filtering in the viewers.

• Nearest Pixel nearest - Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.

• Interpolate Pixels linear - Uses linear filtering between pixels. Use this to get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.

• Mipmap Pixels mipmap - Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail. When the input is 32-bit float format, only nearest filtering will be used (regardless of what is selected).

Passes npasses - Duplicates the operation of the TOP the specified number of times. For every pass after the first it takes the result of the previous pass and replaces the node's first input with the result of the previous pass. One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected TOP's image.

Channel Mask chanmask - Allows you to choose which channels (R, G, B, or A) the TOP will operate on. All channels are selected by default.

Pixel Format format - ⊞ - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.

• Use Input useinput - Uses the input's pixel format.

• 8-bit fixed (RGBA) rgba8fixed - Uses 8-bit integer values for each channel.

• sRGB 8-bit fixed (RGBA) srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace. Note that this does not apply an sRGB curve to the pixel values, it only stores them using an sRGB curve. This means more data is used for the darker values and less for the brighter values. When the values are read downstream they will be converted back to linear. For more information refer to sRGB.

A parameter reference can be setup between any two parameters by putting an expression in one parameter that refers to another parameter. This creates a between the two parameters such that when one changes, the other will change automatically (known in other software as a "constraint").
