3D rendering is the use of software to make objects appear natural. The model created is an image that looks like the actual object. The images are created through 3D software, and they can be either artistic or technical. The model developed through the use of CAD designs is then enhanced through textures, lights, and cameras. The following process will help in understanding rendering better. Though an artist may not go through all the steps simultaneously, the main objective is to understand the client’s vision and deliver the exact results.
After a 3D artist understands the project, they visualize using sketches, plans, and similar images. Then the artist can point out where camera angles will best suit the model.
This step is similar to creating the structure of a building through a physical model. However, in rendering, the design is in a digital form.AR Visual uses 3d modeling software such as Maya, Houdini, and Cinema 4D for the 3D rendering services they offer..
For the model to look natural, specific settings are used to fill in. For example, the materials used can be either glossy or matte. The surfaces can be smoothened or made rough. If it’s a human model, clothing and hair are added. This step is akin to painting or pasting photos on a physical building or wall. However, the modification of the image depends on the kind of software used.
To replicate the lighting in the real world, the artists set up lights at different angles. The light can resemble any time of day or have enough illumination for quality shoots. This step is similar to the lighting preparation made during videography or photoshoot.
This step is exclusively done by the computer and is similar to taking photos physically. How long this step takes depends on the caliber desired, and the intricate details involve and need to be captured. Hence it can take several days or a minute to complete. When a large number of images need to be captured, several computers all in one setting are used and are known as render farms.
Finally, the drafts are presented to the client for revision in a low-resolution setup, enabling the process to go faster. The artist makes modifications to the textures, lights, and scene. These changes are generally made without interfering with the surface of the model. The final delivery to the client is made through the specified size and format. Original files in high resolution are presented for print images, while jpg files are for the web.
Rendering enables a client to see the overall design before the onset of construction and gives room for refinement. For example, for a better arrangement of rooms, rendering can show people’s flow in and out of the building. Rendering is also used in product design and architecture. The different formats used depend on the client’s requirements and set the rendering services’ overall price. The modeling used in rendering is very flexible and open to many possibilities.
