| 9 Version | |
| 10 | |
| 11 Last Modifed Date: October 30, 2014 | |
| 12 | |
| 13 Dependencies | |
| 14 | |
| 15 OpenGL ES 2.0 is required. | |
| 16 | |
| 17 Overview | |
| 18 | |
| 19 Allows clients to subscribe to a set of input uniforms which can | |
| 20 be populated within buffers and used to modify uniform variables within | |
| 21 their programs. | |
| 22 | |
| 23 Decreases percieved latency for operations performed against these | |
| 24 uniforms. | |
| 25 | |
| 26 New Tokens | |
| 27 | |
| 28 Accepted by the <target> parameter of glBindValueBufferCHROMIUM, | |
| 29 glSubscribeValueCHROMIUM, glPopulateSubscribedValuesCHROMIUM and | |
| 30 glUniformValueBufferCHROMIUM | |
| 31 | |
| 32 GL_SUBSCRIBED_VALUES_BUFFER_CHROMIUM 0x924B | |
| 33 | |
| 34 Accepted by the <subscription> parameter of glSubscribeValueCHROMIUM and | |
| 35 glUniformValueBufferCHROMIUM: | |

| 39 New Procedures and Functions | |
| 40 | |
| 41 The command | |
| 42 | |
| 43 void glGenValuebuffersCHROMIUM(GLsizei n, GLuint* buffers) | |
| 44 | |
| 45 Generates value buffer object names. | |
| 46 <n> Specifies the number of value buffer object names to be generated. | |
| 47 <buffers> Specifies an array in which the generated value buffer object | |
| 48 names are stored. | |
| 49 | |
| 50 The command | |
| 51 | |
| 52 void glDeleteValuebuffersCHROMIUM(GLsizei n, const GLuint* valuebuffers) | |
| 53 | |
| 54 Deletes named value buffer objects. | |
| 55 <n> Specifies the number of value buffer objects to be deleted. | |
| 56 <buffers> Specifies an array of value buffer objects to be deleted. | |
| 57 | |
| 58 The command | |
| 59 | |
| 60 boolean glIsValuebufferCHROMIUM(GLuint buffer); | |
| 61 | |
| 62 Returns whether an object is a value buffer object. | |
| 63 <buffer> Specifies the name of a buffer object. | |
| 64 | |
| 65 The command | |
| 66 | |
| 67 void glBindValuebufferCHROMIUM(GLenum target, GLuint buffer); | |
| 68 | |
| 69 Lets you use a named value buffer object. | |
| 70 <target> Specifies the target to which the buffer object is bound. | |
| 71 <buffer> Specifies the name of a buffer object. | |
| 72 | |
| 73 The command | |
| 74 | |
| 75 void glSubscribeValueCHROMIUM(GLenum target, GLenum subscription) | |
| 76 | |
| 77 Subscribes the currently bound buffer object to a subscription target. | |
| 78 <target> Specifies the target to which the buffer object is bound. | |
| 79 <subscription> Specifies the subscription to which the currently bound | |
| 80 buffer object should be subscribed. | |
| 81 | |
| 82 The command | |
| 83 | |
| 84 void glPopulateSubscribedValuesCHROMIUM(GLenum target) | |
| 85 | |
| 86 Populates the currently bound buffer object with all subscription states | |
| 87 to which it is subscribed. | |
| 88 <target> Specifies the target to which the buffer object is bound. | |
| 89 | |
| 90 The command | |
| 91 | |
| 92 void glUniformValueBufferCHROMIUM(GLint location, GLenum target, | |
| 93 GLenum subscription) | |
| 94 | |
| 95 Populates the uniform specified by location within the currently bound | |
| 96 program with the value in the currently bound buffer for the subscription | |
| 97 target. | |
| 98 <location> Specifies the location of the uniform variable to by modified. | |
| 99 <target> Specifies the target to which the buffer object is bound. | |
| 100 <subscription> Specifies the subscription in the currently bound buffer | |
| 101 whose value should be used to populate the uniform. | |
| 102 | |
| 103 Errors | |
| 104 | |
| 105 None. | |
| 106 | |
