Method Details

getBlockSize

public int getBlockSize()

Return the block size. The shape is unaffected.

Returns:

the number of height values in a block

getPosition

public Vec3 getPosition(int x,
 int y)

Copy the location of specified sample. The shape is unaffected.

Parameters:

x - the X coordinate of the sample (≥0, <sampleCount)

y - the Y coordinate of the sample (≥0, <sampleCount)

Returns:

a new location vector

isNoCollision

public boolean isNoCollision(int x,
 int y)

Test whether the shape has a hole at the specified sample. The shape is unaffected.

Parameters:

x - the X coordinate of the sample (≥0, <sampleCount)

y - the Y coordinate of the sample (≥0, <sampleCount)

Returns:

true if there's a hole, otherwise false
