c364879b5f Merge pull request #68 from orange-cpp/feature/screen_to_world
Feature/screen to world
2025-09-09 02:58:32 +03:00
418b7c0e7e Fixes float type conversion in world_to_screen
Fixes a potential type conversion issue by explicitly casting the x-coordinate to float in the world_to_screen test. This prevents possible compiler warnings and ensures the intended behavior.
2025-09-09 02:13:45 +03:00
69f46abce1 Adds projection test for world-to-screen consistency
Adds a test to verify the consistency of world-to-screen and
screen-to-world projections. This ensures that projecting a point
from world to screen and back results in the same point, thereby
validating the correctness of the camera projection transformations.
2025-09-09 01:37:38 +03:00
de61f7a5d8 Adds screen to world space conversion
Adds functionality to convert screen coordinates to world space, including handling for cases where the inverse view projection matrix is singular or when the world position is out of screen bounds.

Also exposes Camera class to unit tests.
2025-09-09 01:31:23 +03:00
07a449b633 Simplifies raycast early exit condition
Combines the infinite length raycast hit check into a single condition.

This clarifies the logic and avoids redundant checks for early exit
in the ray-triangle intersection test, improving performance.
2025-09-08 23:52:35 +03:00
6bb549ef4c Merge pull request #67 from orange-cpp/feature/angle-improvement
Implements angle class with normalization
2025-09-08 20:18:11 +03:00
14fa810ecb Implements angle class with normalization
Adds an angle class with support for different normalization
and clamping strategies. Includes trigonometric functions and
arithmetic operators. Introduces unit tests to verify correct
functionality.

Disables unity builds to address a compilation issue.
2025-09-08 20:15:59 +03:00
b964661030 Merge pull request #66 from orange-cpp/feature/remove-legacy
Removes deprecated Matrix class
2025-09-08 19:59:34 +03:00
9c11551c9a Removes deprecated Matrix class
Removes the deprecated `Matrix` class and its associated source files and unit tests.

This change is to ensure code cleanliness and prevent accidental usage of the slow and outdated `Matrix` class.
The `Mat` class should be used instead.

50054ca937 Acknowledges logo design contribution
Updates the credits to acknowledge the new initial logo design.
2025-09-01 17:04:29 +03:00
63220c0be7 Adds an omath.psd file.
Adds a binary file named omath.psd.
2025-09-01 17:03:31 +03:00
3b6d19782c Updates README with local image links
Updates the README to use local image links instead of Imgur links for the showcase section.

This improves the project's resilience against external link rot and
ensures the images remain accessible even if Imgur experiences issues.
2025-09-01 17:02:23 +03:00
2d58330508 Replaces banner with logo
Replaces the project banner in the README with a dedicated logo.

This change simplifies the banner implementation and improves maintainability
by using a local image file instead of referencing an external URL.
2025-09-01 16:56:43 +03:00
abf57a55ea Updates include paths and removes dependency
Updates the include paths in omath.hpp to be more explicit,
ensuring correct referencing of header files.

Removes unnecessary include of vector3.hpp from vector2.hpp.

2025-09-01 00:02:00 +03:00
d74c66990a Refactors: Moves linear algebra to new directory
Moves linear algebra headers to a new subdirectory to improve project structure.

Updates includes to reflect the directory change.
Adds vcpkg to the tracked repositories.
