what pixels and resolution are?
Before knowing how to select a resolution for your rendering, you may need to know what pixels and resolution are.
In digital imaging, pixels are small squares of color and when arranged together, you get an image that can be viewed and saved.
Resolution is a measurement in pixels for the width and height of a digital file (image) or device capable of displaying digital files (monitor, smart phone, etc.) and is intended only for the digital world has no correlation to any real world measurements.
From presentations and online portfolios to social media posts to printed collateral, every use requires a different resolution. To pick the best resolution for your renders, you need to know not only the necessary width and height in pixels, but also the optimal DPI/PPI. What are those? Let’s see:
PPI
PPI — pixels per inch — defines the pixel density of the resulting image, typically used when exporting vector graphics (in inches) to raster graphics (in pixels).
DPI
DPI — or dots per inch — is a measure of dot density in printed images. It indicates the number of individual dots that can be placed in a line within the span of 1 inch. Dots can represent both methods of printing (ink droplets, laser points for toner adhesion) and scanning (photo receptors).
Is the highest resolution always the best? How do you know which resolution is right for your need?
Though higher resolution does mean better quality, it’s not necessary to pick the highest pixel count in every project. Resolution selection depends on many factors, including:
#Project or source files used (vector graphics, raster textures, etc.)
#Display media (monitor, projector, print, billboard, etc.)
#Purpose of viewing (check design, quality review, marketing, etc.)
Rendering for Print
Every printer / printing service will have documented DPI values to use for a variety of quality outputs and mediums. There is no general rule here, you need to render an image that matches the printer’s specifications. This can be done easily by:
#1.Know what the DPI value of your printer (or service) is
#2.Know what the real world dimensions (width & height) of the print will be
Use online image size calculators to convert these dimensions into pixel values. Use the pixel width and pixel height exactly to render your image.
Example of render size(in pixels) and print size(in mm) connections:
Rendering for online use
In terms of pixel density, 72ppi is the standard resolution for online use. The higher the resolution in pixels, the better the picture looks on a screen. But the higher resolution image needs more time to upload. Plus, you do not want a few visuals to take up the entire space on your hosting server. So, you should pick the resolution smartly
Animation resolution
When select a resolution for your animation, you should keep in mind that the animation contains several frames per second-about 30 frames. Since each 3D animated image takes more time to process, if you want to increase the animation, it will take more time to render the resolution. Also, rendering resolution affects FPS. Higher resolution will require more GPU power to render the image.
Animation resolution often depends on the medium on which it will be projected.
Standard resolution for animation rendering:
FPS
One of the animation dimensions is FPS. In simple terms, this is the number of Frames per Second played by the system when watching a video or in computer games.
What does FPS affect? As a rule, the higher the score, the better, as the movements will be smoother and more realistic. Low values result in stuttering (playing at a constant frame rate) or dropping frames (with a variable frame rate). Interestingly, if the value is too high, for example, if you run an old game on a powerful computer, the opposite effect can be observed – flickering due to too fast frame rates.
What should be the frame rate? For computer games, the minimum comfortable value is 30 FPS. To view the video in standard quality, you need a frequency of 24 frames, video in good quality (Full HD and higher) – 30, for 3D – twice as much, that is, 60.
Now you may know how to pick the best resolution for architectural 3D visualization. Naturally, a lot of details can be custom and unique from project to project. High resolution is required to obtain high-quality rendering and animation. You need to keep this in mind when processing your final renderings, as this will significantly affect their quality.
