How can I move the camera without moving the point of interest?
To move the camera or light along a single axis without moving the point of interest, Ctrl-drag (Windows), or Command-drag (Mac OS) the axis. To move the camera or light freely without moving the point of interest, drag the camera icon or light icon. To move the point of interest, drag the point of interest icon .
Is it easier to move the camera around a scene?
Just as it’s easier in the real world to move cameras through and around a scene than it is to move and rotate the scene itself, it’s often easiest to get different views of a composition by setting up a camera layer and moving it around in a composition.
How does HoloLens work to locate the camera?
Locating the Device Camera in the World When HoloLens takes photos and videos, the captured frames include the location of the camera in the world and the lens model of the camera. This allows applications to reason about the position of the camera in the real world for augmented imaging scenarios.
How is a locatable camera used in mixed reality?
Many mixed reality applications use a recognizable image or visual pattern to create a trackable point in space. This is then used to render objects relative to that point or create a known location.
How are point lights different from directional lights?
When considering point lights, the main difference regarding directional lights is that now we have a position for the light instead of a direction. This implies that the light direction is not constant across all fragments/vertices as it was for direction lights. Besides that, everything remains just like for directional lights.
How is a triangle lit by a point light?
In the figure below we have a triangle being lit by a directional light (left) and a point light (right). The vertex shader now receives a light position instead of a light direction, and it must compute the light’s direction for each vertex. It is assumed that the light’s position is in camera space.
Why do you need to use point lights?
However point lights are important for simulating the vast majority of light sources. Pretty much anything that is illuminated with a light bulb is a point light. Point lights have a position of origin and a color, they do not require a direction.
