Class: capability

Certain system (hardware related) capabilites can be queried for support here.

Methods:

Method overview:


bufferblit ()
returns: (boolean)
returns support for blitting from one to another renderfbo/backbuffer via rcmdbufferblit
dot3normalmap ()
returns: (boolean)
returns support for VID_NORMAL combiner in shader system.
drawbuffers ()
returns: (int)
returns maximum number of multiple render targets for color drawbuffers
fbo ()
returns: (boolean)
returns support for framebufferobjects (fbo), allow enhanced rendertotexture. Especially rendering to multiple drawbuffers or textures with larger size than window. renderfbo, renderbuffer, rcmdfbobind ... need this capability.
hwshadow ()
returns: (boolean)
returns support for shadow map comparison and depth textures
pbo ()
returns: (boolean)
returns support for pixel buffer objects, useful for loading/retrieven image data asynchronously.
pointsprites ()
returns: (boolean)
returns if particle points can be rendered as sprites (quad-like textured).
r2vb ()
returns: (boolean)
returns support for render 2 vertexbuffer functionality, useful to capture vertex stream output.
renderbuffermsaa ()
returns: ([int])
returns number of maximum samples of multisampled renderbuffers, or nil if no support is given.
stenciltwosided ()
returns: (boolean)
returns support for two-sided stencil testing
stencilwrap ()
returns: (boolean)
returns support for wrapped increment and decrement
tex3d ()
returns: (boolean)
returns support for 3d textures
tex3dsize ()
returns: (int)
returns maximum dimension of 3d texture
texabgr ()
returns: (boolean)
returns support for ABGR texture data
texanisotropic ()
returns: ([float])
returns maximum anisotropic value for texture filtering, if supported.
texarray ()
returns: (boolean)
returns support for array textures, typically requires capability.cg_sm4 as well.
texarraylayers ()
returns: (int)
returns how many texture layers in array textures are available.
texautomipmap ()
returns: (boolean)
returns support for automatic mipmaps
texbgr ()
returns: (boolean)
returns support for BGR,BGRA texture data
texbuffer ()
returns: (boolean)
returns support for buffer textures, typically requires capability.cg_sm4 as well.
texcomb_combine4 ()
returns: (boolean)
returns support for combine4 in texcombiners
texcomb_crossbar ()
returns: (boolean)
returns support for access to all texture units in texcombiners
texcomb_dot3 ()
returns: (boolean)
returns support for dot3 in texcombiners
texcomb_modadd ()
returns: (boolean)
returns support for modulated add functions in texcombiners
texcomb_subtract ()
returns: (boolean)
returns support for subtract in texcombiners
texcompress ()
returns: (boolean)
returns support for texture compression
texcube ()
returns: (boolean)
returns support for cubemap textures
texdds ()
returns: (boolean)
returns support for dds texture loading
texdepthstencil ()
returns: (boolean)
returns support for a packed format of 24bit depth and 8bit stencil texture.
texfloat ()
returns: (boolean)
returns support for float16 and float32 textures
texinteger ()
returns: (boolean)
returns support for integer textures, typically requires capability.cg_sm4 as well.
texnp2 ()
returns: (boolean)
returns support for non power of two texture dimensions. Currently only supported for 3d textures. For 2d textures use rectangle capability.
texrectangle ()
returns: (boolean)
returns support for rectangle textures
texvertex ()
returns: (int)
returns number of textures that can be accessed in vertex shader
vbo ()
returns: (boolean)
returns support for vbo
vramsize ()
returns: (int)
