Entre outras funcionalidades, o programa pode ser utilizado para renderiza\u00e7\u00e3o de alta precis\u00e3o de cenas complexas e processamento de cenas muito grandes, que requerem a execu\u00e7\u00e3o distribu\u00edda de c\u00e1lculos em um cluster de v\u00e1rios computadores. O c\u00f3digo do aplicativo \u00e9 escrito em C++ e distribu\u00eddo sob a licen\u00e7a Apache 2.0. Para a renderiza\u00e7\u00e3o na tela, s\u00e3o utilizados OpenGL e a biblioteca GLFW.      <\/p>\n<p>A cena a ser renderizada pode ser carregada em formatos comuns ou criada usando n\u00f3s de gr\u00e1fico de cena (scene graph). O suporte inclui a importa\u00e7\u00e3o de modelos no formato MTL com materiais para renderiza\u00e7\u00e3o fotorrealista, anima\u00e7\u00f5es 3D no formato glTF, texturas no formato UDIM, part\u00edculas volum\u00e9tricas esparsas (por exemplo, nuvens) no formato VDB, nuvens de pontos no formato PCD (Point Cloud Data) e perfis de ilumina\u00e7\u00e3o no formato EULUMDAT (.ldt). O estado do gr\u00e1fico de cena pode ser salvo ou carregado no formato JSON.       <\/p>\n<p>Recursos avan\u00e7ados, widgets para a interface do usu\u00e1rio e manipuladores de importa\u00e7\u00e3o de dados podem ser conectados na forma de plugins. Por exemplo, est\u00e3o dispon\u00edveis plugins para visualiza\u00e7\u00e3o de dados m\u00e9dicos no formato DICOM, gera\u00e7\u00e3o de paisagens a partir de mapas de altura, processamento de grandes grupos de objetos padr\u00e3o (grama, \u00e1rvores), simula\u00e7\u00e3o de eventos astron\u00f4micos, visualiza\u00e7\u00e3o de dados cient\u00edficos no formato VTK, e assim por diante.      <\/p>\n<p>Para simular o comportamento da luz, \u00e9 suportado o uso do m\u00e9todo de tra\u00e7ado de raios. A visualiza\u00e7\u00e3o pode ser feita em volume ou em plano. Suporta ilumina\u00e7\u00e3o global fotorrealista considerando as propriedades f\u00edsicas dos materiais e efeitos de sombreamento avan\u00e7ados (sombras, transpar\u00eancia e sombreamento 'Ambient occlusion'). \u00c9 poss\u00edvel criar scripts para realizar opera\u00e7\u00f5es em modo batch, por exemplo, para renderizar imagens em um sistema sem monitor, selecionar \u00e1reas para renderiza\u00e7\u00e3o, configurar a c\u00e2mera, par\u00e2metros de renderiza\u00e7\u00e3o e da cena.      <center>  <video controls=\"\" style=\"width: 700px; height: 400px; max-width:100%\"><source src=\"http:\/\/www.ospray.org\/ospray_studio\/images\/DizzyDrone15.mp4\" type=\"video\/mp4\"><\/video>  <\/center>      <\/p>\n<p>Na nova vers\u00e3o do OSPRay Studio:  <\/p>\n<ul>\n<li class=\"l\"> Adicionada a suporte para a funcionalidade do motor OSPRay que surgiu na vers\u00e3o 3.1.\n<li class=\"l\"> A interface do usu\u00e1rio foi integrada com suporte a materiais adicionais suportados pelo motor OSPRay.\n<li class=\"l\"> Adicionado suporte para a API OpenEXR v2.x e v3.x.\n<li class=\"l\"> Foi implementada a identifica\u00e7\u00e3o de altera\u00e7\u00f5es nos arquivos em modo ass\u00edncrono para atualiza\u00e7\u00e3o autom\u00e1tica de texturas.\n<li class=\"l\"> Na API para plugins, foi implementada a possibilidade de acesso \u00e0s classes MainWindow e ArcballCamera.\n<li class=\"l\"> No modo em lote, h\u00e1 suporte para renderiza\u00e7\u00e3o distribu\u00edda usando MPI.  <\/ul>\n<p>Al\u00e9m disso, vale destacar a publica\u00e7\u00e3o, h\u00e1 alguns dias, de uma nova vers\u00e3o do mecanismo de renderiza\u00e7\u00e3o 3D OSPRay 3.1, utilizado no OSPRay Studio 1.0. O mecanismo est\u00e1 sendo desenvolvido como parte de um projeto maior chamado Intel Rendering Framework, voltado para o desenvolvimento de ferramentas de visualiza\u00e7\u00e3o computacional de c\u00e1lculos cient\u00edficos SDVis (Software Defined Visualization), que incluem a biblioteca de tra\u00e7ado de raios Embree, o sistema de renderiza\u00e7\u00e3o fotorrealista GLuRay, a biblioteca para remo\u00e7\u00e3o de ru\u00eddo em imagens oidn (Open Image Denoise) e o sistema de rasteriza\u00e7\u00e3o computacional OpenSWR. O c\u00f3digo foi escrito em C++ e publicado sob a licen\u00e7a Apache 2.0.    <\/p>\n<p>O OSPRay \u00e9 principalmente direcionado ao uso em aplica\u00e7\u00f5es interativas para renderiza\u00e7\u00e3o de cena em tempo real. O mecanismo pode funcionar sem depend\u00eancia de GPU, permitindo o uso da biblioteca em uma ampla gama de dispositivos, desde esta\u00e7\u00f5es de trabalho at\u00e9 n\u00f3s em clusters computacionais. Para garantir desempenho adequado, utiliza-se intensamente multithreading e vetoriza\u00e7\u00e3o com instru\u00e7\u00f5es baseadas em SIMD, como Intel SSE4, AVX, AVX2 e AVX-512. A renderiza\u00e7\u00e3o pode ser distribu\u00edda em v\u00e1rios n\u00f3s do cluster (suporte a MPI), permitindo, por exemplo, o uso do OSPRay para organizar a renderiza\u00e7\u00e3o de imagens de muito alta resolu\u00e7\u00e3o em paredes de v\u00eddeo, onde uma \u00fanica imagem \u00e9 formada por um conjunto de pain\u00e9is LCD separados.    <\/p>\n<p>Entre as melhorias no OSPRay 3.1:  <\/p>\n<ul>\n<li class=\"l\"> Suporte ao uso de texturas emissivas com materiais brilhantes.\n<li class=\"l\"> Foram adicionados \u00e0 lista de objetos esf\u00e9ricos suportados o 'disco' (OSP_DISC) e o 'disco orientado' (OSP_ORIENTED_DIS).\n<li class=\"l\"> Adicionados modos de repeti\u00e7\u00e3o espelhada e imers\u00e3o de textura na borda (edge texture wrap).\n<li class=\"l\"> Suporte ao modo OSPTextureWrapMode foi adicionado para todas as texturas.\n<li class=\"l\"> Suporte completo para o mapeamento de texturas no formato glTF foi implementado.\n<li class=\"l\"> Adicionada suporte para remo\u00e7\u00e3o de ru\u00eddo e corre\u00e7\u00e3o de tom para dados no buffer.\n<li class=\"l\"> Apoio ao desfoque de movimento foi implementado para objetos em movimento ao usar GPU.
