What are VCL and FMX Frameworks and How They Work with Dicom VCL
VCL and FMX are two different frameworks for creating graphical user interfaces (GUIs) in Delphi and C++ Builder. VCL stands for Visual Component Library and FMX stands for FireMonkey Cross Platform Framework. Both frameworks provide a set of components, classes, and properties that allow you to design and customize your GUIs.
VCL is the older and more mature framework that is designed for Windows development. It is based on the Windows API and uses native Windows controls for most of its components. VCL applications have a native look and feel on Windows and can take advantage of Windows-specific features, such as themes, menus, dialogs, etc. VCL applications can only run on Windows platforms.
FMX is the newer and more flexible framework that is designed for cross-platform development. It is based on OpenGL ES and uses custom-drawn controls for all of its components. FMX applications have a consistent look and feel across different platforms and can adapt to different screen sizes, resolutions, orientations, etc. FMX applications can run on Windows, Linux, Android, iOS, and HTML5 platforms.
Dicom VCL supports both VCL and FMX frameworks, which means you can create DICOM applications for any platform you want. You can use the same Dicom VCL components and classes in both frameworks, with some minor differences in properties and methods. You can also switch between frameworks easily by changing the target platform in your project options.
What is OpenGL ES and How It Works with Dicom VCL
OpenGL ES is a cross-platform API for rendering advanced 2D and 3D graphics on embedded and mobile systems, such as consoles, phones, appliances, and vehicles. It is a royalty-free and well-defined subset of the desktop OpenGL API, suitable for low-power devices. It provides a flexible and powerful interface between software and graphics acceleration hardware.
OpenGL ES has several versions, each adding new features and functionality to the previous ones. The latest version is OpenGL ES 3.2, which brings the mobile API's functionality significantly closer to its desktop counterpart - OpenGL. OpenGL ES 3.2 supports features such as multiple render targets, geometry and tessellation shaders, advanced blending modes, texture compression, etc.
Dicom VCL uses OpenGL ES for 3D rendering of DICOM images. It supports both VCL and FMX frameworks, which means you can create applications for Windows, Linux, Android, iOS, and HTML5 platforms. Dicom VCL uses OpenGL ES 2.0 or higher, depending on the target platform and device capabilities. You can use the Dicom Viewer component to display and manipulate DICOM images in 3D, such as zooming, panning, rotating, slicing, measuring, etc. You can also use the Dicom Volume component to create volume rendering of DICOM images, such as maximum intensity projection (MIP), minimum intensity projection (MinIP), average intensity projection (AIP), etc.
What is Volume Rendering and How It Works with Dicom VCL
Volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, such as a DICOM image. Volume rendering is useful for visualizing and analyzing the internal structures and features of the data set, without extracting any surfaces or contours.
Volume rendering assumes that the data set represents a 3D scalar field, where each voxel (volume element) has a single value that corresponds to some physical property, such as density, intensity, or temperature. Volume rendering also assumes that the data set is illuminated by light sources and that the light interacts with the voxels in various ways, such as emission, absorption, and scattering.
Volume rendering can be performed in several ways, depending on the desired quality and performance. One common method is ray casting, which traces rays from the camera through the volume and samples the voxels along the ray. The samples are then mapped to colors and opacities using a transfer function, and composited together to form the final pixel color. Ray casting can produce high-quality images, but it is computationally intensive and requires a lot of memory.
Another common method is texture-based volume rendering, which uses 3D textures to store and render the volume data. Texture-based volume rendering can be implemented using two approaches: slice-based and splatting. Slice-based rendering slices the volume into parallel planes and renders them as textured polygons. Splatting renders each voxel as a textured point sprite that covers a circular area on the screen. Texture-based volume rendering can achieve high performance and interactivity, but it may introduce artifacts such as aliasing and gaps.
Dicom VCL supports texture-based volume rendering using both slice-based and splatting approaches. You can use the Dicom Volume component to create volume rendering of DICOM images using either approach. You can also adjust various parameters, such as transfer function, lighting model, shading mode, interpolation mode, etc., to customize the appearance of the volume rendering. Dicom VCL supports both VCL and FMX frameworks, which means you can create applications for Windows, Linux, Android, iOS, and HTML5 platforms.
