Modules

axis_angle_4d module doml.axis_angle_4d: Represents a 3D rotation of a given radians about an axis represented as an unit 3D vector. This class uses double-precision components.
frustum_intersection module doml.frustum_intersection: Efficiently performs frustum intersection tests by caching the frustum planes of an arbitrary transformation {@link Matrix4d matrix}. This class is preferred over the frustum intersection methods in {@link Matrix4d} when many objects need to be culled by the same static frustum.
frustum_ray_builder module doml.frustum_ray_builder: Provides methods to compute rays through an arbitrary perspective transformation defined by a {@link Matrix4d}. This can be used to compute the eye-rays in simple software-based raycasting/raytracing. To obtain the origin of the rays call {@link #origin(Vector3d)}. Then to compute the directions of subsequent rays use {@link #dir(double, double, Vector3d)}.
geometry_utils module doml.geometry_utils: Useful geometry methods.
interpolation_d module doml.interpolation_d: Contains various interpolation functions.
intersection_d module doml.intersection_d: Contains intersection and distance tests for some 2D and 3D geometric primitives.
math module doml.math: Contains fast approximations of some {@link java.lang.Math} operations. By default, {@link java.lang.Math} methods will be used by all other DOML classes. In order to use the approximations in this class, start the JVM with the parameter <code>-DDOML.fastmath</code>. There are two algorithms for approximating sin/cos: <ol> <li>arithmetic <a href="http://www.java-gaming.org/topics/DOML-1-8-0-release/37491/msg/361815/view.html#msg361815">polynomial approximation</a> contributed by roquendm <li>theagentd's <a href="http://www.java-gaming.org/topics/extremely-fast-sine-cosine/36469/msg/346213/view.html#msg346213">linear interpolation</a> variant of Riven's algorithm from <a href="http://www.java-gaming.org/topics/extremely-fast-sine-cosine/36469/view.html">http://www.java-gaming.org/</a> </ol> By default, the first algorithm is being used. In order to use the second one, start the JVM with <code>-DDOML.sinLookup</code>. The lookup table bit length of the second algorithm can also be adjusted for improved accuracy via <code>-DDOML.sinLookup.bits=<n></code>, where <n> is the number of bits of the lookup table.
matrix_2d module doml.matrix_2d: Contains the definition of a 2x2 matrix of doubles, and associated functions to transform it. The matrix is column-major to match OpenGL's interpretation, and it looks like this: m00 m10 m01 m11
matrix_3d module doml.matrix_3d: Contains the definition of a 3x3 matrix of doubles, and associated functions to transform it. The matrix is column-major to match OpenGL's interpretation, and it looks like this: m00 m10 m20 m01 m11 m21 m02 m12 m22
matrix_3x2d module doml.matrix_3x2d: Contains the definition of a 3x2 matrix of doubles, and associated functions to transform it. The matrix is column-major to match OpenGL's interpretation, and it looks like this: m00 m10 m20 m01 m11 m21
matrix_4d module doml.matrix_4d: Contains the definition of a 4x4 Matrix of doubles, and associated functions to transform it. The matrix is column-major to match OpenGL's interpretation, and it looks like this: m00 m10 m20 m30 m01 m11 m21 m31 m02 m12 m22 m32 m03 m13 m23 m33
matrix_4x3d module doml.matrix_4x3d: Contains the definition of an affine 4x3 matrix (4 columns, 3 rows) of doubles, and associated functions to transform it. The matrix is column-major to match OpenGL's interpretation, and it looks like this: m00 m10 m20 m30 m01 m11 m21 m31 m02 m12 m22 m32
mem_util module doml.mem_util: Helper class to do efficient memory operations on all DOML objects, NIO buffers and primitive arrays. This class is used internally throughout DOML, is undocumented and is subject to change. Use with extreme caution!
options module doml.options: Utility class for reading system properties.
quaternion_d module doml.quaternion_d: Quaternion of 4 double-precision doubles which can represent rotation and uniform scaling.
quaternion_d_interpolator module doml.quaternion_d_interpolator: Computes the weighted average of multiple rotations represented as {@link Quaterniond} instances. Instances of this class are not thread-safe.
ray_aabb_intersection module doml.ray_aabb_intersection: This is an implementation of the <a href="http://www.cg.cs.tu-bs.de/media/publications/fast-rayaxis-aligned-bounding-box-overlap-tests-using-ray-slopes.pdf">Fast Ray/Axis-Aligned Bounding Box Overlap Tests using Ray Slopes</a> paper. It is an efficient implementation when testing many axis-aligned boxes against the same ray. This class is thread-safe and can be used in a multithreaded environment when testing many axis-aligned boxes against the same ray concurrently.
rounding_mode module doml.rounding_mode: Rounding modes.
tests module doml.tests
vector_2d module doml.vector_2d: Represents a 2D vector with double-precision.
vector_2i module doml.vector_2i: Represents a 2D vector with integral-precision.
vector_3d module doml.vector_3d: Contains the definition of a Vector comprising 3 doubles and associated transformations.
vector_3i module doml.vector_3i: Contains the definition of a Vector comprising 3 ints and associated transformations.
vector_4d module doml.vector_4d: Contains the definition of a Vector comprising 4 doubles and associated transformations.
vector_4i module doml.vector_4i: Contains the definition of a Vector comprising 4 ints and associated transformations.
