Lighting & Environment

In order to prepare your scene for a beautiful 3D meeting you might need to look at changing some of the lighting and environment settings. Let's have a look at what we offer inside the editor.

Background:

a. Colour: You can choose any colour from the colour pallet or by adding your own HEX, RGBA, or HSLA code. The colour change in the background will not reflect in any way on the model. It will just replace the background colour.

b. Environment: Introducing an background will make your scene look more realistic especially when looking at exterior views from the inside.

Environment

Here you have the option of selecting which environment you wish to load. As of now we have prepared for you 3 main environments; Venice Sunset, Clarence Night and Qwantani Puresky.

What does it mean for you inside Studio 3DX Meet:

1. With this background type (HDR) you will be able to reflect on surfaces such as windows by changing the Shading Mode and by changing the Exposure Level you will can get an imitation of time change in your scene.

Exposure

I think Adobe explains it quite simply that exposure is the amount of light that reaches your camera and the right exposure is all about balance.

Exposure is one of the most fundamental photography terms. When you take a picture, you press the shutter button to open a camera’s aperture, and light streams in, triggering a response from a sensor. Exposure is the amount of light that reaches your camera’s sensor, creating visual data over a period of time. That time period could be fractions of a second or entire hours. The right exposure is a balancing act. Overexposure leads to overexposed highlights and faded-looking images. Underexposed images are dark and hard to see. Learn these basics to better understand camera exposure and discover how to get the right exposure for your work. Source: Adobe, Get the correct exposure for your photos.

What does it mean for you inside Studio 3DX Meet:

1. In the case of our viewer we introduced HDR backgrounds that hold the information for at least three exposure and that's why you are able to slide between really dark to really bright.

Tone Mapping

Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range images in a medium that has a more limited dynamic range. There's an interesting article on Skylum on understanding HDR and tone mapping if you want to learn more.

What does it mean for you inside Studio 3DX Meet:

1. By changing the Tone Mapping option from None, to Linear, Reinhard, Cineon, ACES Flimic will bring a different atmosphere to your scenery.

Shading Mode

In the case of shading mode we are looking at 4 main options; Unlit, Simple, Standard and Toon. It becomes quickly apparent that the Standard Shading Mode is the most powerful as the reflections on the glass and the dark places inside the model that are created from this shading mode are more realistic.

What does it mean for you inside Studio 3DX Meet:

1. It's important to play around with the settings and mix n' match them
2. You might that the only shading mode that is affected by the environment is standard shading

Example #1: Switching between Shading Modes without a Background

Unlit	Simple
Standard	Toon

Example #2

Standard	Toon

Ambient light intensity

Ambient light generally means the light that is already in the scene that effects the objects inside them.

What does it mean for you inside Studio 3DX Meet:

1. In the context of our viewer changing the intensity of the Ambient light introduces or reduces the light in the scene.

Directional light intensity

Directional light is more straight forward as this light gets emitted in a specific direction. This light will behave as though it is infinitely far away and the rays produced from it are all parallel. The common use case for this is to simulate daylight; the sun is far enough away that its position can be considered to be infinite, and all light rays coming from it are parallel.

What does it mean for you inside Studio 3DX Meet:

1. This light can cast shadows on your model
2. Light rays from a Directional Light are parallel and it uses the orthographic camera to calculate the shadows
