Point

public Point()

Point

public Point(java.lang.String name,
             Vector3f[] vertex,
             Vector3f[] normal,
             ColorRGBA[] color,
             Vector2f[] texture)

Constructor instantiates a new Point object with a given set of data. Any data may be null, except the vertex array. If this is null an exception is thrown.

Parameters:

name - the name of the scene element. This is required for identification and comparison purposes.

vertex - the vertices or points.

normal - the normals of the points.

color - the color of the points.

texture - the texture coordinates of the points.

             java.nio.FloatBuffer vertex,
             java.nio.FloatBuffer normal,
             java.nio.FloatBuffer color,
             TexCoords coords)

Constructor instantiates a new Point object with a given set of data. Any data may be null, except the vertex array. If this is null an exception is thrown.

Parameters:

name - the name of the scene element. This is required for identification and comparison purposes.

vertex - the vertices or points.

normal - the normals of the points.

color - the color of the points.

coords - the texture coordinates of the points.

Method Detail

reconstruct

public void reconstruct(java.nio.FloatBuffer vertices,
                        java.nio.FloatBuffer normals,
                        java.nio.FloatBuffer colors,
                        TexCoords coords)

Description copied from class: Geometry

reconstruct reinitializes the geometry with new data. This will reuse the geometry object.

Overrides:

reconstruct in class Geometry

Parameters:

vertices - the new vertices to use.

normals - the new normals to use.

colors - the new colors to use.

coords - the new texture coordinates to use (position 0).

generateIndices

public void generateIndices()

findCollisions

public void findCollisions(Spatial scene,
                           CollisionResults results,
                           int requiredOnBits)

Description copied from class: Spatial

checks this spatial against a second spatial, any collisions are stored in the results object.

Specified by:

findCollisions in class Spatial

Parameters:

scene - the scene to test against.

results - the results of the collisions.

requiredOnBits - considered a collision only if these bits are 'on' in both 'this' and the 'scene' spatial.

hasCollision

public boolean hasCollision(Spatial scene,
                            boolean checkTriangles,
                            int requiredOnBits)

Description copied from class: Spatial

Checks this spatial against a second spatial for collisions.

Specified by:

hasCollision in class Spatial

Parameters:

scene - the scene to test against.

checkTriangles - check for collisions on triangle accuracy level

requiredOnBits - considered a collision only if these bits are 'on' in both 'this' and the 'scene' spatial.

Returns:

true if any collision were found

isAntialiased

public boolean isAntialiased()

Returns:

true if points are to be drawn antialiased

setAntialiased

public void setAntialiased(boolean antialiased)

Sets whether the point should be antialiased. May decrease performance. If you want to enabled antialiasing, you should also use an alphastate with a source of SourceFunction.SourceAlpha and a destination of DB_ONE_MINUS_SRC_ALPHA or DB_ONE.

Parameters:

antialiased - true if the line should be antialiased.

getPointSize

public float getPointSize()

Returns:

the pixel size of each point.

setPointSize

public void setPointSize(float size)

Sets the pixel width of the point when drawn. Non anti-aliased point sizes are rounded to the nearest whole number by OpenGL.

Parameters:

size - The size to set.

getIndexBuffer

public java.nio.IntBuffer getIndexBuffer()

setIndexBuffer

public void setIndexBuffer(java.nio.IntBuffer indices)

write

public void write(JMEExporter e)
           throws java.io.IOException

Specified by:

write in interface Savable

Overrides:

write in class Geometry

Throws:

java.io.IOException

read

public void read(JMEImporter e)
          throws java.io.IOException

Specified by:

read in interface Savable

Overrides:

read in class Geometry

Throws:

java.io.IOException

draw

public void draw(Renderer r)

Description copied from class: Geometry

draw prepares the geometry for rendering to the display. The renderstate is set and the subclass is responsible for rendering the actual data.

Overrides:

draw in class Geometry

Parameters:

r - the renderer that displays to the context.
