Note: This option only works when also using the `--flat` option. +Use the `--cursor-scale` option to change the scale of the cursor. By default the scale is 1.0, except in sphere mode where it's 0.0. Set the scale to 0 to hide the cursor. + To rotate and move the video to be in front of you, pull the trigger on the vr controller or press `w` on your keyboard while the vr video player is focused. You can also use the select/back button on an xbox controller while the application is focused or send the SIGUSR1 signal to the application to do the same thing like using the following command: ``` diff --git a/src/main.cpp b/src/main.cpp index 42e9a2f..4370a24 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -319,6 +319,8 @@ private: // X compositor stbi_uc *arrow_image_data = nullptr; int arrow_image_width = 0; int arrow_image_height = 0; + + float cursor_scale_uniform[2]; }; @@ -408,7 +410,7 @@ void dprintf( const char *fmt, ... ) } static void usage() { - fprintf(stderr, "usage: vr-video-player [--flat] [--left-right|--right-left|--plane] [--stretch|--no-stretch] [--zoom zoom-level] <window_id>\n"); + fprintf(stderr, "usage: vr-video-player [--flat] [--left-right|--right-left|--plane] [--stretch|--no-stretch] [--zoom zoom-level] [--cursor-scale scale] <window_id>\n"); exit(1); } @@ -450,6 +452,7 @@ CMainApplication::CMainApplication( int argc, char *argv[] ) const char *projection_arg = nullptr; const char *view_mode_arg = nullptr; bool zoom_set = false; + bool cursor_scale_set = false; for(int i = 1; i < argc; ++i) { if(strcmp(argv[i], "--flat") == 0) { @@ -463,9 +466,10 @@ CMainApplication::CMainApplication( int argc, char *argv[] ) zoom = atof(argv[i + 1]); ++i; zoom_set = true; - /*} else if(strcmp(argv[i], "--cursor-scale") == 0 && i < argc - 1) { + } else if(strcmp(argv[i], "--cursor-scale") == 0 && i < argc - 1) { cursor_scale = atof(argv[i + 1]); - ++i;*/ + ++i; + cursor_scale_set = true; } else if(strcmp(argv[i], "--left-right") == 0) { if(view_mode_arg) { fprintf(stderr, "Error: --left-right option can't be used together with the %s option\n", view_mode_arg); @@ -518,10 +522,17 @@ CMainApplication::CMainApplication( int argc, char *argv[] ) zoom = 1.0; } + if(cursor_scale < 0.01f || (!cursor_scale_set && projection_mode == ProjectionMode::SPHERE)) { + cursor_scale = 0.01f; + } + printf("src window id: %ld, zoom: %f\n", src_window_id, zoom); // other initialization tasks are done in BInit memset(m_rDevClassChar, 0, sizeof(m_rDevClassChar)); + + cursor_scale_uniform[0] = 0.0f; + cursor_scale_uniform[1] = 0.0f; }; @@ -1337,6 +1348,7 @@ bool CMainApplication::CreateAllShaders() " vec2 cursor_diff = (v2CursorLocation + arrow_size_frag) - v2UVcoords;\n" " vec4 arrow_col = texture(arrow_texture, (arrow_size_frag - cursor_diff) / arrow_size_frag);\n" " vec4 col = texture(mytexture, v2UVcoords);\n" + " if(arrow_size_frag.x < 0.001 || arrow_size_frag.y < 0.001) arrow_col.a = 0.0;\n" " outputColor = mix(col, arrow_col, arrow_col.a);\n" "}\n" ); @@ -1723,12 +1735,11 @@ void CMainApplication::AddCubeToScene( const glm::mat4 &mat, std::vector<float> arrow_ratio = width_ratio * 2.0; } - float v[2]; - v[0] = 0.01 * cursor_scale; - v[1] = v[0] * arrow_ratio * ((float)arrow_image_height / (float)arrow_image_width); + cursor_scale_uniform[0] = 0.01 * cursor_scale; + cursor_scale_uniform[1] = cursor_scale_uniform[0] * arrow_ratio * ((float)arrow_image_height / (float)arrow_image_width); glUseProgram( m_unSceneProgramID ); - glUniform2fv(m_nArrowSizeLocation, 1, &v[0]); + glUniform2fv(m_nArrowSizeLocation, 1, &cursor_scale_uniform[0]); glUseProgram( 0 ); } @@ -2013,10 +2024,10 @@ void CMainApplication::RenderScene( vr::Hmd_Eye nEye ) float m[2]; // -10 offset is the distance between the edge of the arrow.png image to the arrow itself - m[0] = (mouse_x - 10) / (float)window_width; - m[1] = (mouse_y - 10) / (float)window_height; + m[0] = mouse_x / (float)window_width; + m[1] = mouse_y / (float)window_height; - if(view_mode != ViewMode::PLANE && m[0] > 0.5f) + if(view_mode != ViewMode::PLANE && m[0] >= 0.5f) m[0] -= 0.5f; /* // TODO: Set this as an option? @@ -2057,6 +2068,16 @@ void CMainApplication::RenderScene( vr::Hmd_Eye nEye ) m[0] += offset; } + + float drawn_arrow_width = cursor_scale_uniform[0] * window_width; + float drawn_arrow_height = cursor_scale_uniform[1] * window_height; + float arrow_drawn_scale_x = drawn_arrow_width / (float)arrow_image_width; + float arrow_drawn_scale_y = drawn_arrow_height / (float)arrow_image_height; + + int cursor_offset = -10; + m[0] += (cursor_offset * arrow_drawn_scale_x) / (float)window_width; + m[1] += (cursor_offset * arrow_drawn_scale_y) / (float)window_height; + glUniform2fv(m_nCursorLocation, 1, &m[0]); glBindVertexArray( m_unSceneVAO ); |
