Using Perlin Noise effect with Director 11: perlinNoise() method helps you to create great looking noise effect. Following is a simple example of how you can achieve the Perlin Noise effect.

Draw a paint member and name it as 'myMember'
Attach the following script to the Sprite as beginFrame handler and Play the movie.

on beginsprite me
myList = [point(0,1), point(5,5)] --List of Points
member("myMember").Image.perlinNoise(5, 5, 2, 2, true, true, [#channelOptions:7, #grayscale:false, #offsets:myList])
end

Antialiasing Text with Director 11: With the antiAliasType property, we can control whether a text cast member is rendered using anti-aliasing to produce high-quality rendering. Following are the available antialiasing options;

Auto – #AutoAlias (Uses the font file information for anti-aliasing.)
Grayscale All - #GrayScaleAllAlias (Enables grayscale anti-aliasing for all text members.)
Subpixel All - #SubpixelAllAlias (Enables sub-pixel anti-aliasing for all text members.)
Grayscale Larger Than - #GrayscaleLargerThanAlias (Enables grayscale anti-aliasing for font sizes greater than the specified threshold.)
None - #NoneAlias (turns off anti-aliasing for the current cast member.)

Physics in Director: Intro 2: We can create 3d physics world where rigid bodies with different coefficients of restitution and friction are falling under gravity. One can change the default attributes (coefficient of friction, restitution) of the rigid bodies and observe the effects. Some of the physics methods and properties used are as follows:

Init()- initializes the physics world with the specified 3D cast member.
gravity- assigns the acceleration due to gravity in the physics world.
contacttolerance- assigns the penetration depth between rigid bodies for the collision to be detected.
createrigidbody()- method creates a rigid body with the specified proxy shape.
friction- assigns friction to the specified rigid body if used with a rigid body reference.
restitution-assigns restitution to the specified rigid body if used with a rigid body reference.
mass- assigns mass to the rigid body.
destroy()- stops the simulation of the world and frees all the resources in the world.
simulate()- simalates forward the physics world by some specified time.The step time depends on the timestepmode set during the init call

Physics in Director: Intro 3: RAYCASTING is the use of ray-surface intersection tests to solve a variety of problems in computer graphics. It solves the general problem of determining the first object intersected by a ray or all the objects coming in the direction of a ray. It is an image order algorithms used in computer graphics to render three dimensional scenes to two dimensional screens by following rays of light from the eye of the observer to a light source. The high speed of calculation made ray casting a handy method for the rendering in early real-time 3D video games. The idea behind ray casting is to shoot rays from the eye, one per pixel, and find the closest object blocking the path of that ray - think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye normally sees through that pixel.

Some of the physics methods and properties used are as follows:

Init()- initializes the physics world with the specified 3D cast member.
contacttolerance- assigns the penetration depth between rigid bodies for the collision to be detected.
createrigidbody()- method creates a rigid body with the specified proxy shape.
mass- assigns mass to the rigid body.
destroy()- stops the simulation of the world and frees all the resources in the world.
simulate()- simalates forward the physics world by some specified time.The step time depends on the timestepmode set during the init call.
Raycastclosest()-returns the reference of the closest rigid body or terrain that is found along the ray from the specified origin and specified direction. The method also returns the point of contact, contact normal, and the distance from the origin of the ray.
Raycastall()-This method will return the references of all the rigid bodies or terrains that are found along the ray from the specified origin and specified direction. The method also returns the point of contact, contact normal, and the distance from the origin of the ray.
