The difference between rendering and not rendering

Rendering is the last process of CG (except for post-production, of course) and it is also the stage that finally makes your image fit your 3D scene.

In English it is called Render, and some call it shading, but generally Shade is called shading and Render is called rendering. (Recommended learning: PS video tutorial)

Because the two words Render and Shade are two completely different concepts in 3D software, although their functions are very similar, they have different.

Shade is a display scheme that generally appears in the main window of 3D software. It plays the same role as the wireframe of the 3D model to assist in observing the model. Obviously, the shading mode makes it easier for us to understand the structure of the model than the wireframe mode, but it is just a simple display. It is called light and dark shading in digital images

. In advanced 3D software like Maya, you can also use Shade to display simple lighting effects, shadow effects and surface texture effects. Of course, high-quality shading effects require the support of a professional 3D graphics display card, which can accelerate and Optimize the display of 3D graphics. But no matter how optimized it is, it cannot turn the displayed three-dimensional graphics into high-quality images. This is because Shade uses a real-time display technology, and the speed of the hardware is limited. It cannot feedback the reflection and refraction in the scene in real time. and other ray tracing effects.

In real work, we often need to output models or scenes into image files, video signals or film films, which must go through the Render program.

The Shade window provides a very intuitive and real-time basic surface shading effect. Depending on the capabilities of the hardware, it can also display texture maps, light source effects and even shadow effects, but all of this is rough, especially in Without hardware support, its display may even be irrational and disorderly.

Rendering will be more realistic than not rendering, but the time required for rendering is often very long. The picture effect after rendering through Photoshop 3D is obviously better and more beautiful than the picture effect without rendering.

"Rendering" Filters create cloud patterns, refraction patterns, and simulated light reflections in images. You can also manipulate objects in 3D space and create texture fills from grayscale files to produce 3D-like lighting effects.

Layered Clouds

Generate cloud patterns using randomly generated values ​​between the foreground and background colors. This filter blends cloud data with existing pixels in the same way that Difference mode blends colors. The first time you choose this filter, parts of the image are inverted into a cloud pattern. After applying this filter a few times, it creates a pattern of ridges and veins that resembles the texture of marble.

Lighting Effects

enables you to produce countless lighting effects on RGB images by changing 17 lighting styles, 3 lighting types, and 4 sets of lighting properties. You can also use textures from grayscale files, called bump maps, to produce 3D-like effects and store your own styles for use in other images.

Lens Flare

Simulates the refraction caused by bright light hitting the camera lens. Specify the location of the center of the halo by clicking anywhere on the image thumbnail or dragging its crosshairs.
